3 Description

The TPS38700-Q1 device is an integrated

multichannel voltage sequencer with a window

watchdog and I2C programmable available in a 24-pin

4 mm x 4 mm VQFN package.

This multichannel voltage sequencer is ideal for

systems that require precise power up and/or

power down sequencing and can be interfaced with

multichannel voltage supervisors. The device defaults

to preprogrammed OTP options but the I2C can

reprogram the power up and power down sequence,

watchdog settings, and sequence timing options if

needed.

Flexible and programmable voltage rail sequencing

capabilities, low quiescent current, and small

footprint allow this device to meet most application

requirements.
