Detailed Description for MIC2564A-1BSM
Product Overview
The MIC2564A-1BSM from Microchip Technology is a dual serial PCMCIA/CardBus power switch designed for surface-mount systems. It provides a 3:4 input-to-output configuration with four high-side N-channel outputs and a serial interface. The device supports load voltages of 3.3 V, 5 V, or 12 V and provides 120 mA maximum output current. A typical on-resistance of 1.3 ohm, fixed current limiting, overtemperature protection, and a status flag are included.
Key Features
- PCMCIA switch type with four high-side N-channel outputs
- 3:4 input-to-output ratio and serial control interface
- Load voltage options include 3.3 V, 5 V, and 12 V
- Maximum output current is 120 mA with typical 1.3 ohm on-resistance
- Fixed current limiting, overtemperature protection, and status flag are included
- Non-inverting input type and 24-SSOP surface-mount package
- Operating temperature range is -40°C to 85°C (TA)
Applications
- PCMCIA and CardBus slot power control
- Serial-controlled high-side switching for 3.3 V, 5 V, or 12 V loads
- Protected load switching in compact surface-mount designs
Design & Procurement Notes
Designers should confirm that output current remains within the 120 mA maximum and that load voltage selection matches 3.3 V, 5 V, or 12 V. The serial interface and non-inverting input require control signal planning, while the status flag can support output state indication. Fixed current limiting and overtemperature protection should be evaluated against expected fault conditions. The 24-SSOP surface-mount package and -40°C to 85°C (TA) range support compact board layouts within these limits.
