DS1705ESA/T&R Equivalent & Substitute Parts

Part Overview

The DS1705ESA/T&R is a Power Management Integrated Circuit (PMIC) supervisor manufactured by Analog Devices Inc./Maxim Integrated. This component functions as a single-channel power-on reset supervisor with push-pull totem pole output, designed for monitoring supply voltage and generating active-low reset signals. The DS1705ESA/T&R is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DS1705ESA/T&R are qualified based on the following electrical and mechanical parameters:

• Voltage Threshold: 4.65V (exact match required)
• Output Configuration: Push-Pull, Totem Pole (exact match required)
• Reset Logic: Active Low (exact match required)
• Package Type: 8-SOIC form factor (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Number of Voltages Monitored: 1 channel (exact match required)

The substitute parts identified below maintain electrical compatibility through identical threshold voltage, output topology, reset polarity, and thermal operating range. Packaging variants (Tape & Reel, Tube, Cut Tape & Digi-Reel) represent different distribution formats of the same die and are mechanically and electrically interchangeable in the 8-SOIC footprint.

Parameter Comparison

Engineering Selection Recommendations

DS1705ESA+T&R is the direct equivalent of DS1705ESA/T&R with identical electrical specifications and thermal operating range. This part transitions from obsolete to active product status and achieves ROHS3 compliance, making it suitable for new designs and production continuity where RoHS compliance is required.

ADM705ARZ, ADM705ARZ-REEL, and ADM705ARZ-REEL7 are manufacturer-recommended alternatives from Analog Devices Inc. These parts maintain the same voltage threshold, output topology, reset polarity, and package footprint. The reset timeout specification differs at 160ms minimum versus 130ms minimum on the DS1705 series. All three ADM705 variants are active products with ROHS3 compliance and REACH unaffected status. Selection among these three variants depends on packaging and distribution requirements: ADM705ARZ is supplied in Tube format, while ADM705ARZ-REEL and ADM705ARZ-REEL7 are supplied in Cut Tape & Digi-Reel format.

Frequently Asked Questions (FAQ)

Q: Can DS1705ESA+T&R be used as a direct replacement for DS1705ESA/T&R?

A: Yes. DS1705ESA+T&R is electrically and mechanically identical to DS1705ESA/T&R. The primary difference is product status (active versus obsolete) and RoHS compliance (ROHS3 versus non-compliant). Both parts share the same 4.65V threshold, push-pull totem pole output, active-low reset logic, 130ms minimum reset timeout, and 8-SOIC package footprint.

Q: What is the difference between DS1705 and ADM705 series?

A: Both series are single-channel power-on reset supervisors with identical voltage thresholds (4.65V), output configurations (push-pull totem pole), reset polarity (active low), and package types (8-SOIC). The primary difference is reset timeout specification: DS1705 specifies 130ms minimum, while ADM705 specifies 160ms minimum. This difference does not affect pin compatibility or circuit board layout.

Q: Are ADM705ARZ, ADM705ARZ-REEL, and ADM705ARZ-REEL7 electrically identical?

A: Yes. These three part numbers represent the same integrated circuit in different packaging formats. ADM705ARZ is supplied in Tube packaging, while ADM705ARZ-REEL and ADM705ARZ-REEL7 are supplied in Cut Tape & Digi-Reel format. Electrical specifications, thermal performance, and 8-SOIC footprint are identical across all three variants.

Q: Is the 8-SOIC package footprint identical across all substitute parts?

A: Yes. All substitute parts use the 8-SOIC package with 0.154" width and 3.90mm body width. PCB layout and component placement are directly interchangeable.

Q: Do all substitute parts meet RoHS compliance requirements?

A: DS1705ESA/T&R is RoHS non-compliant. DS1705ESA+T&R and all ADM705 variants (ADM705ARZ, ADM705ARZ-REEL, ADM705ARZ-REEL7) are ROHS3 compliant. Selection depends on regulatory requirements for the end application.
