FEATURES

DESCRIPTION

2

•

Input Voltage: 1.0V to 3.6V

switch with user programmable features. The device

•

contains four N-channel MOSFETs that can operate

–

over an input voltage range of 1.0V to 3.6V. The

–

usage with processors that have limited GPIO

–

available. The rise time of the TPS22993 device is

–

internally controlled in order to avoid inrush current.

The TPS22993 has five programmable slew rate

•

VBIAS voltage range: 4.5V to 17.2V

options, four ON-delay options, and four quick output

–

Suitable for 2S/3S/4S Li-ion Battery

discharge (QOD) resistance options.

Topologies

The channels of the device can be controlled via

•

1.2A Max Continuous Current per Channel

•

Quiescent Current

–

Single Channel < 9µA

address pins can be tied high or low to assign seven

unique device addresses.

–

All Four Channels < 17µA

•

Shutdown Current (all four channels) < 6µA

The TPS22993 is available in a space-saving RLW

package (0.4mm pitch) and is characterized for

•

Four 1.2V Compatible GPIO Control Inputs

operation over the free-air temperature range of

•

–40°C to 85°C.

–

On/Off Control

–

Programmable Slew Rate Control (5

options)

–

Programmable ON-delay (4 options)

–

Programmable Output Discharge (4

options)
