3 Description

The TPS22925 product family consists of four

devices: TPS22925B, TPS22925BN, TPS22925C,

and TPS22925CN. Each device is a 9-mΩ, singlechannel

load switch with a controlled slew rate.

The devices contain an N–channel MOSFET that can

operate over an input voltage range of 0.65 V to

3.6 V and can support a maximum continuous current

of 3 A. This continuous current enables the devices to

be used across multiple designs and end equipments.

Each of the TPS22925 devices provides reverse

current blocking when disabled allowing for power

supply protection and power multiplexing capabilities.

The controlled rise time for the device greatly reduces

inrush current caused by large bulk load

capacitances, thereby reducing or eliminating power

supply droop. When operating with an input voltage

of 3.6 V, the TPS22925Bx devices feature a 97 μs

rise time and the TPS22925Cx devices feature an

810 μs rise time.

The TPS22925 family of devices can help reduce the

total solution size by offering an optional integrated,

150-Ω pull–down resistor for quick output discharge

(QOD) when the switch is turned off. Each of the

TPS22925 devices is available in a 0.9 mm × 1.4

mm, 0.5-mm pitch, 0.4-mm height 6–pin wafer chip

scale package (WCSP) allowing for smaller, more

integrated designs. The WCSP and 9 mΩ of onresistance

allow use in space constrained, battery

powered applications. The device is characterized for

operation over the free–air temperature range of

–40°C to +105°C.
