TPS3780DDRYR

Texas Instruments · Monitors & Reset Circuits · uSON-6(1x1.5)

TPS3780DDRYR from Texas Instruments, in a uSON-6(1x1.5). 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	SENSE1	input	Connected to the monitored voltage through an external resistor divider; OUT1 is asserted when the voltage at this pin drops below VIT-.
2	GND	power_in	Ground.
3	SENSE2	input	Connected to the monitored voltage through an external resistor divider; OUT2 is asserted when the voltage at this pin drops below VIT-.
4	OUT2	output	Open-drain output for SENSE2 on the TPS3780, driven low when SENSE2 falls below VIT- and released high after SENSE2 rises above VIT+; it can be pulled up to 6.5 V independent of VDD and requires a pull-up resistor.
5	OUT1	output	Open-drain output for SENSE1 on the TPS3780, driven low when SENSE1 falls below VIT- and released high after SENSE1 rises above VIT+; it can be pulled up to 6.5 V independent of VDD and requires a pull-up resistor.
6	VDD	power_in	Supply voltage input of 1.5 V to 6.5 V, with a 0.1-µF ceramic capacitor recommended close to the pin (required for VDD < 1.5 V).
