TPS2220BPWPR Equivalent & Substitute Parts

Part Overview

The TPS2220BPWPR is a Power Switch/Driver IC in the 24-HTSSOP package, designed for PCMCIA switch applications with a 4:2 input-to-output ratio and 1A maximum output current. This component features high-side output configuration with serial interface control and integrated fault protection including current limiting and over-temperature monitoring.

The TPS2220BPWPR is classified as Obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and production continuity. Substitute parts must maintain compatibility across electrical specifications, package form factor, and operational characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS2220BPWPR is determined by the following critical parameters:

• Package Compatibility: 24-PowerTSSOP form factor with identical 0.173" width and 4.40mm dimensions
• Electrical Interface: Serial interface control with status flag capability
• Output Configuration: High-side switching topology with 2 outputs
• Load Voltage Support: 3.3V, 5V, and 12V operation
• Current Capacity: 1A maximum output current
• On-Resistance: 95mOhm typical Rds(on)
• Fault Protection: Current limiting and over-temperature protection
• Temperature Range: -40°C to 85°C operating specification
• Compliance: ROHS3 compliance and MSL 2 rating

The TPS2210APWPR qualifies as a parametric equivalent substitute with one functional difference: the input-to-output ratio is 3:2 instead of 4:2. All other electrical, thermal, and mechanical parameters remain identical, and the package footprint is fully compatible.

Parameter Comparison

Engineering Selection Recommendations

The TPS2210APWPR serves as a direct parametric equivalent for the obsolete TPS2220BPWPR across all critical electrical and mechanical specifications. Both components maintain identical compliance certifications (ROHS3), moisture sensitivity ratings (MSL 2), and thermal operating ranges (-40°C to 85°C).

The primary design consideration is the input-to-output ratio difference: TPS2220BPWPR provides 4:2 switching capability while TPS2210APWPR provides 3:2 switching capability. This distinction affects the number of input control lines available for PCMCIA switch management and must be evaluated against specific application requirements.

Both parts are available in identical 24-PowerTSSOP packages with matching footprints, enabling direct PCB layout compatibility. The TPS2210APWPR is currently listed as discontinued at DiGi Electronics, indicating limited ongoing availability. Component selection should prioritize current inventory status and supply chain continuity alongside functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can the TPS2210APWPR directly replace the TPS2220BPWPR on existing PCBs?

A: Yes, the TPS2210APWPR is pin-compatible and footprint-compatible with the TPS2220BPWPR due to identical 24-PowerTSSOP packaging. However, the 3:2 input-to-output ratio differs from the 4:2 ratio of the original part, requiring verification that your application does not depend on the additional input control line.

Q: What is the significance of the input-to-output ratio difference?

A: The ratio indicates the number of independent input control lines relative to output switches. The TPS2220BPWPR supports 4 input control lines managing 2 outputs, while the TPS2210APWPR supports 3 input control lines managing 2 outputs. Applications requiring all 4 input control lines cannot use the TPS2210APWPR as a substitute.

Q: Are the electrical performance characteristics identical between these parts?

A: Yes. Both parts share identical maximum output current (1A), on-resistance (95mOhm typical), load voltage support (3.3V, 5V, 12V), fault protection mechanisms, and operating temperature range (-40°C to 85°C).

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the TPS2220BPWPR and TPS2210APWPR are ROHS3 compliant with MSL 2 moisture sensitivity ratings and identical REACH and ECCN classifications.

Q: What is the current availability status of these parts?

A: The TPS2220BPWPR is classified as Obsolete. The TPS2210APWPR is listed as Discontinued at DiGi Electronics. Inventory availability should be confirmed with authorized distributors before design commitment.
