MIC2562A-1BTS

Overview

The MIC2562A-1BTS is a PCMCIA/CardBus socket power controller manufactured by Microchip Technology. It integrates three independent N-channel power switches and two additional outputs, housed in a 16-TSSOP package. The device manages system power supply distribution to VCC and VPP rails. Key electrical parameters include a maximum output current of 200mA per channel and a typical on-resistance (Rds On) of 70mOhm. It supports operating supply voltages of 3.3V and 5V, with an off-time maximum of 1us. The component operates within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates multiple independent N-channel power switches for efficient power distribution management.
• Features logic interface with non-inverting input type for straightforward control integration.
• Includes status flag functionality to monitor switch states and system health.

Applications

• PCMCIA socket power control
• CardBus socket power management
• System power supply distribution to VCC and VPP rails

Procurement Notes

Verify the specific suffix 'BTS' against the manufacturer's official documentation to confirm pinout compatibility and thermal characteristics. Ensure the source provides valid RoHS compliance data. Cross-reference the 16-TSSOP package dimensions with mechanical drawings before integration. Confirm that the supplier offers genuine Microchip Technology components to avoid counterfeit risks.

Selection Notes

Select this component when designing systems requiring dedicated power sequencing for PCMCIA or CardBus interfaces. The integrated nature reduces external component count compared to discrete solutions. Consider the 200mA current limit and 70mOhm resistance for thermal management planning. Verify voltage compatibility with the target 3.3V or 5V system rails during the initial design phase.
