Overview
The AP2142SG-13 is a high-side dual power switch IC from Diodes Incorporated, designed for power distribution applications. It operates within an input voltage range of 2.7 V to 5.5 V and supports a continuous output current of 0.5 A per channel with an 0.8 A current limit. The device features a maximum on-resistance of 160 mΩ (typical 140 mΩ) and utilizes active-low enable logic. Packaged in an 8-pin SOIC, it functions reliably between -40°C and +85°C, offering turn-on and turn-off delays of approximately 50 µs and 10 µs respectively.
Feature Summary
- Dual-channel high-side switching architecture for independent load control
- Integrated current limiting protects downstream circuits from overcurrent conditions
- Active-low enable logic simplifies interface with standard digital controllers
Applications
- USB port power distribution and protection
- Peripheral device power sequencing
- Battery-powered equipment load management
Procurement Notes
Verify the specific suffix against the manufacturer datasheet to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the ordering number with official Diodes Incorporated documentation to validate active status and availability before finalizing procurement plans.
Selection Notes
Select this component when dual-channel isolation is required within a compact footprint. The 2.7 V minimum operating voltage makes it suitable for single-cell lithium battery systems. Compare the 160 mΩ on-resistance against thermal dissipation requirements for the specific load currents to ensure adequate performance without external cooling.
Part Context
This part belongs to the AP214x series of power switches, which are optimized for portable electronics. Unlike single-channel variants such as the AP2141, this model provides two isolated outputs. It shares the same voltage and current specifications as other dual-channel members but differs in packaging options like the SG suffix indicating SOIC format.
Replacement Considerations
The AP2146MPG-13 is a confirmed substitute offering identical dual-channel functionality, 0.5 A output, and 2.7 V–5.5 V operation. Verify pin compatibility and thermal characteristics during substitution.
