MAX1607ESA Equivalent & Substitute Parts

Part Overview

The MAX1607ESA is a Power Switch/Driver IC featuring a 1:1 P-Channel configuration rated for 700mA output current in an 8-SOIC package. This component is classified as Obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The device operates across a 2.7V to 5.5V load voltage range with adjustable current limiting, over-temperature protection, and UVLO (Under-Voltage Lock-Out) fault protection suitable for USB switching applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAX1607ESA is determined by the following critical parameters:

• Package Compatibility: 8-SOIC form factor (0.154", 3.90mm Width)
• Voltage Range: 2.7V ~ 5.5V load voltage operation
• Output Configuration: High-side switching topology
• Fault Protection: Current limiting, over-temperature, and UVLO protection
• Interface Type: On/Off control logic
• Mounting Type: Surface mount

Substitute parts are grouped into two categories based on channel type:

Category 1 - P-Channel Direct Equivalent: MAX1607ESA+ maintains identical electrical characteristics and channel polarity, differing only in product status (Active vs. Obsolete) and RoHS compliance.

Category 2 - N-Channel Alternatives: TPS2020D, TPS2041AD, TPS2041BD, and TPS2045D provide functionally equivalent high-side switching with N-Channel topology. These require inverting logic at the control input and differ in current ratings and on-resistance specifications. BD2061AFJ-E2 offers N-Channel switching with higher current capacity (1A) and additional reverse current protection.

Parameter Comparison

Engineering Selection Recommendations

MAX1607ESA+ (Recommended Primary Substitute)

MAX1607ESA+ is the direct functional equivalent with identical electrical specifications, package, and channel polarity. The primary advantage is Active product status with ROHS3 compliance, addressing the obsolescence of the original MAX1607ESA. This part requires no circuit topology changes and maintains non-inverting logic control. Select this part for designs requiring direct pin-for-pin compatibility and P-Channel switching characteristics.

TPS2041BD (Recommended for N-Channel Designs)

TPS2041BD provides 500mA output current with -40°C to 85°C operating temperature matching the original specification. The N-Channel topology requires inverting control logic but offers Active product status and ROHS3 compliance. On-resistance of 70mOhm is comparable to the original 60mOhm specification. This part is suitable for applications where N-Channel switching is acceptable and control logic inversion is feasible.

BD2061AFJ-E2 (High Current Alternative)

BD2061AFJ-E2 delivers 1A maximum output current with non-inverting control logic, eliminating the need for logic inversion required by Texas Instruments N-Channel alternatives. However, this part carries Obsolete product status. Select this part only when higher current capacity is required and obsolescence is acceptable for the application timeline.

TPS2020D (Lower Current Applications)

TPS2020D is suitable for applications requiring only 200mA output current. It features the lowest on-resistance (33mOhm) among substitutes and includes a Status Flag output. Operating temperature extends to 125°C (TJ). This part is appropriate for reduced-power designs where the lower current rating is sufficient.

Frequently Asked Questions (FAQ)

Q: Can MAX1607ESA+ be used as a direct replacement for MAX1607ESA?

A: Yes. MAX1607ESA+ is electrically and functionally identical with the same 700mA current rating, 60mOhm on-resistance, and non-inverting control logic. The primary differences are Active product status and ROHS3 compliance. No circuit modifications are required.

Q: What is the key difference between P-Channel and N-Channel substitutes?

A: P-Channel devices (MAX1607ESA+) use non-inverting control logic where a high input signal turns the switch on. N-Channel alternatives (TPS2020D, TPS2041AD, TPS2041BD, TPS2045D) require inverting logic where a low input signal turns the switch on. Circuit control logic must be adapted accordingly.

Q: Which N-Channel substitute best matches the original 700mA specification?

A: No N-Channel substitute exactly matches 700mA. TPS2041AD and TPS2041BD both provide 500mA, representing the closest match. BD2061AFJ-E2 offers 1A capacity but carries Obsolete status. Selection depends on whether the application can operate at reduced current or requires higher capacity.

Q: Are all substitutes compatible with the 8-SOIC package footprint?

A: MAX1607ESA+, TPS2020D, TPS2041AD, TPS2041BD, and TPS2045D use standard 8-SOIC packaging. BD2061AFJ-E2 uses 8-SOP-J packaging, which has the same 0.154" (3.90mm) width but may have minor pitch or lead configuration differences. Verify PCB footprint compatibility before selection.

Q: What is the significance of RoHS compliance for these parts?

A: MAX1607ESA is RoHS non-compliant, while all active substitutes (MAX1607ESA+, TPS2020D, TPS2041AD, TPS2041BD, TPS2045D) are ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, select ROHS3-compliant parts. BD2061AFJ-E2 is also ROHS3 compliant despite Obsolete status.

Q: How do current limiting characteristics differ between substitutes?

A: MAX1607ESA and MAX1607ESA+ feature adjustable current limiting, allowing threshold customization via external components. All N-Channel alternatives (TPS2020D, TPS2041AD, TPS2041BD, TPS2045D) and BD2061AFJ-E2 use fixed current limiting thresholds. Adjustable limiting provides design flexibility but requires additional circuitry.

Q: Can BD2061AFJ-E2 be used despite Obsolete status?

A: BD2061AFJ-E2 is Obsolete but offers 1A current capacity and non-inverting control logic without circuit modification. Use this part only if higher current is required and long-term availability is not a concern. For new designs, prioritize Active parts (MAX1607ESA+ or Texas Instruments alternatives).
