Texas Instruments' TPS38700 is an integrated multichannel voltage sequencer with a window watchdog and I2C programmable that is available in a 24-pin 4 mm x 4 mm VQFN package. This sequencer is ideal for systems that require precise power-up and/or power-down sequencing and can be interfaced with multichannel voltage supervisors.

The TPS38700 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. The flexible and programmable voltage rail sequencing capabilities, low quiescent current, and small footprint allow this voltage sequencer to meet most application requirements.
