1 Features 3 Description

1• Integrated Single Load Switch The TPS22910A, TPS22912C, and TPS22913B/C

are small, low rON load switches with controlled turn

• Four Pin Wafer-Chip-Scale Package (Nom) on. The device contains a P-channel MOSFET that

– 0.9 mm × 0.9 mm, 0.5-mm Pitch, 0.5-mm can operate over an input voltage range of 1.4 V to

Height (YZV) 5.5 V. The switch is controlled by an on/off input

(ON), which is capable of interfacing directly with low- • Input Voltage Range: 1.4 V to 5.5 V

voltage GPIO control signals.

• Low ON-Resistance

ON = 60 mΩ at VIN = 5 V

devices provide reverse current protection in ON and

– rON = 61 mΩ at VIN = 3.3 V OFF states. An internal reverse voltage comparator

– rON = 74 mΩ at VIN = 1.8 V disables the power-switch when the output voltage

VRCP, to quickly (10 μs typ) stop the flow of current

• 2-A Maximum Continuous Switch Current towards the input side of the switch. Reverse current

• Low Threshold Control Input protection is always active, even when the power•

Controlled Slew-rate switch is disabled. Additionally, under-voltage lockout

(UVLO) protection turns the switch off if the input • Under-Voltage Lock Out voltage is too low.

• Full-Time Reverse Current Protection

The TPS22913B/C contains a 150-Ω on-chip load

• Quick Output Discharge Transistor (TPS22913B/C resistor for quick output discharge when the switch is Devices) turned off.

2 Applications This family of devices have various slew rate options

to avoid inrush current (see Device Comparison

• Notebook Computer and Ultrabook™ Table for details), are available in an ultra-small,

• Tablets and Set-Top-Boxes space-saving 4-pin WCSP packages, and are

characterized for operation over the free-air • Portable Industrial / Medical Equipment

temperature range of –40°C to 85°C.
