Multichannel voltage sequence generator with integrated window watchdog

Texas Instruments TPS38700/TPS38700-Q1 Power Sequence generator is a multi-channel voltage sequence generator with integrated window watchdog in a 24-pin 4mm x 4mm VQFN package. The TPS38700/TPS38700-Q1 is designed for use in systems requiring precise power-on and/or power-off timing and can be connected to multi-channel voltage monitors. By default, the sort generator uses the pre-programmed OTP option, but I2C can reprogram the power-on and power-off timing controls, watchdog Settings, and sequence timing options if required.

The TI TPS38700/TPS38700-Q1 power supply sequence generator has the advantages of flexible and programmable voltage rail timing function, low static current and small size. These characteristics enable the device to meet most application requirements. The TPS38700-Q1 device meets AEC-Q100 certification for automotive applications.
