3 Description

The TPS38700 device is an integrated multichannel

voltage sequencer with a window watchdog and

I2C programmable in a 24-pin 4mm x 4mm VQFN

package.

This multichannel voltage sequencer is designed

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. TPS38700 is designed to be

used along with monitoring parts like TPS389006/

TPS3890008.
