Overview
The MIC2564A-1YTS is a dual serial PCMCIA/CardBus power controller manufactured by Microchip Technology. It functions as a high-side power switch matrix designed to manage VCC and VPP voltages for two PC Card slots. The device integrates a 3:4 input-to-output ratio, allowing control of four independent N-channel outputs via three serial data inputs. It operates within a supply voltage range of 2.7V to 5.5V and supports load voltages of 3.3V, 5V, and 12V. The component is housed in a 24-TSSOP package with a typical on-resistance of 1.3 ohms and provides a maximum output current of 120mA per channel.
Feature Summary
- Serial interface control for managing multiple power channels efficiently
- Integrated over-temperature latch and fixed current limit protection
- Supports both VCC and VPP voltage regulation for PCMCIA applications
Applications
- PCMCIA card slot power distribution
- CardBus power switching matrices
- Portable computer power management systems
Procurement Notes
Verify the specific suffix '1YTS' against the official Microchip datasheet to confirm pinout and electrical characteristics. Note that this component may be classified as Not Recommended for New Designs (NRND) or End-of-Life (EOL). Confirm RoHS compliance status and moisture sensitivity level requirements before integration into new production schedules.
Selection Notes
Select this component when designing systems requiring serial-controlled power sequencing for PCMCIA or CardBus interfaces. Ensure the design accommodates the 3:4 input/output architecture and the 24-TSSOP footprint. Verify that the required load currents remain within the 120mA limit and that the operating temperature range aligns with system constraints.
Part Context
This part belongs to the MIC2564 series of power distribution switches. It was originally developed by Micrel Semiconductor, which was subsequently acquired by Microchip Technology. The series is specialized for controlling power delivery in legacy portable computing standards, specifically targeting the voltage regulation needs of PC Card and CardBus expansion slots.
Replacement Considerations
Publicly confirmed substitute part numbers include TPS2224APWP from Texas Instruments. Evaluate compatibility regarding package dimensions, serial interface protocols, and electrical ratings before substitution.
