The TPS22925 product family consists of four devices: TPS22925B, TPS22925BN, TPS22925C,
and TPS22925CN. Each device is a 9-mΩ, single-channel load switch with a controlled slew
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 on-resistance 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.
