The TPS38700S-Q1 device is an integrated multichannel voltage sequencer with a window watchdog and I 2C 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 I 2C 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.
