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.
