10 Power-Supply Recommendations

The TPS3779-Q1 and TPS3780-Q1 are designed to operate from an input voltage supply range between 1.5 V and 5.5 V. An input supply capacitor is not required for this device; however, good analog practice is to place a 0.1-µF or greater capacitor between the VDD pin and the GND pin. This device has a 7-V absolute maximum rating on the VDD pin. If the voltage supply providing power to VDD is susceptible to any large voltage transient that can exceed 7 V, additional precautions must be taken.

For applications where SENSEx is greater than 0 V before VDD, and is subject to a startup slew rate of less than 200 mV per 1 ms, the output can be driven to logic high in error. To correct the output, cycle the SENSEx lines below VIT– or sequence SENSEx after VDD.
