What are the key features of TPS2231PWG4?
- Octal 8-channel power switch architecture manages multiple PCMCIA or CardBus slot supplies independently from a single 20-pin TSSOP device
- Integrated intelligent load-switch control with fault detection and reporting reduces external protection circuitry and simplifies hot-plug power management
- Compact 20-pin TSSOP package with 0.25 mm pitch minimises board real estate in notebook computers and embedded PC-card socket controllers
What is TPS2231PWG4 used for?
TPS2231PWG4 is used in laptop PC-card and CardBus socket controllers, embedded industrial computing boards, and legacy PCMCIA interface designs where multiple supply rails must be independently switched and protected. Its integrated fault reporting and 8-channel architecture enable a single IC to manage the complete power sequence for dual-slot PCMCIA designs, reducing component count and improving system reliability.

Frequently Asked Questions
How many independent power switch channels does TPS2231PWG4 provide for PCMCIA slot management?
TPS2231PWG4 provides 8 independent power switch channels within a single 20-pin TSSOP package. This is sufficient to control all the required supply voltages — Vcc, Vpp1, Vpp2, and auxiliary rails — for dual-slot PCMCIA or CardBus sockets from a single device, eliminating the need for multiple discrete switches.
Does TPS2231PWG4 include built-in overcurrent or fault protection for the switched outputs?
Yes, TPS2231PWG4 integrates intelligent fault detection on its switched outputs. When an overcurrent or short-circuit event is detected on any channel, the device asserts a fault flag that a host controller can read, allowing the system to shut down the affected supply rail and prevent damage to the PCMCIA card or host circuitry.
Which package does TPS2231PWG4 use and how does this compare in board footprint to a discrete FET-based solution?
TPS2231PWG4 uses a 20-pin TSSOP package with 0.25 mm lead pitch, occupying approximately 25 mm² of board area. A discrete solution using 8 individual load-switch FETs with gate drivers and protection resistors would typically require 50–80 mm², making TPS2231PWG4 roughly 2–3× more compact while eliminating at least 20 passive components.
