TPS3780BQDBVRQ1

Texas Instruments · Supervisor And Reset ICs · SOT-23-6

TPS3780BQDBVRQ1 from Texas Instruments, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VDD power_in Supply voltage input that must be connected to a 1.5-V to 5.5-V supply, with a 0.1-µF ceramic capacitor placed close to the pin (required for VDD < 1.5 V).
2 OUT1 output Open-drain output for SENSE1 (TPS3780 variant) that is driven low when SENSE1 falls below VIT- and goes high after SENSE1 rises above VIT+, can be pulled up to 5.5 V independent of VDD, and requires a pullup resistor.
3 OUT2 output Open-drain output for SENSE2 (TPS3780 variant) that is driven low when SENSE2 falls below VIT- and goes high after SENSE2 rises above VIT+, can be pulled up to 5.5 V independent of VDD, and requires a pullup resistor.
4 SENSE2 input Monitored voltage input connected through an external resistor divider; OUT2 is asserted when the voltage at this pin drops below VIT-.
5 GND power_in Ground reference pin for the device.
6 SENSE1 input Monitored voltage input connected through an external resistor divider; OUT1 is asserted when the voltage at this pin drops below VIT-.
