Detailed Description for MIC2564A-1YTS
Product Overview
The Microchip Technology MIC2564A-1YTS is a PCMCIA switch/driver with a serial interface and four high-side N-channel outputs. It supports 3.3 V, 5 V, and 12 V load voltages from a 3.3 V to 12 V supply, provides 120 mA maximum output current, and uses a surface-mount 24-TSSOP package.
Key Features
- Serial interface with a 3:4 input-to-output ratio and four outputs.
- High-side N-channel output configuration and non-inverting inputs.
- 120 mA maximum output current with typical 1.3 ohm Rds On.
- Fixed current limiting, over-temperature protection, and status flag.
- Operating temperature range of -40°C to +85°C (TA).
Applications
- PCMCIA card power switching.
- Serial-controlled high-side load switching for 3.3 V, 5 V, and 12 V rails.
- Low-current peripheral power management with status feedback.
Design & Procurement Notes
For design use, drive the non-inverting serial inputs and monitor the status flag. Check load current against the 120 mA maximum and account for typical 1.3 ohm Rds On in voltage-drop and thermal calculations. Match the 3.3 V to 12 V supply and 3.3 V, 5 V, or 12 V load rails to the system architecture.
