3 Description

The TPS38700S-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 an excellent

choice 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.

SYNC on the TPS38700S-Q1 allows designers to

have more control over how their system powers

up. The TPS38700S-Q1 acheives this by only firing

the following enable signal when the current rail has

powered up to an acceptable level with the use of the

SYNC signal. In addition TPS38700S-Q1 allows for

custom delay options. TPS38700S-Q1 is designed to

be used with the TPS389006-Q1.
