TPS37044BJOFDDFR

Texas Instruments · Supervisor And Reset ICs · TSOT-23-8

TPS37044BJOFDDFR from Texas Instruments, in a TSOT-23-8. 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	Power supply input; bypass to GND with a 0.1 µF capacitor.
2	SENSE1	input	Input connected directly to the monitored voltage; for TPS37044, SENSE1 or SENSE2 going outside the window threshold asserts RESET1, and the pin may be left floating if unused.
3	SENSE2	input	Input connected directly to the monitored voltage; for TPS37044, SENSE1 or SENSE2 going outside the window threshold asserts RESET1, and the pin may be left floating if unused.
4	GND	power_in	Ground.
5	SENSE3	input	Input connected directly to the monitored voltage; for TPS37044, SENSE3 or SENSE4 going outside the window threshold asserts RESET2, and the pin may be left floating if unused.
6	SENSE4	input	Input connected directly to the monitored voltage; for TPS37044, SENSE3 or SENSE4 going outside the window threshold asserts RESET2, and the pin may be left floating if unused.
7	RESET2	output	Active-low open-drain reset output that is asserted when the monitored voltage is outside its overvoltage or undervoltage window (for TPS37044, SENSE3 or SENSE4), stays asserted during the reset timeout after returning in window, and requires an external pull-up resistor.
8	RESET1	output	Active-low open-drain reset output that is asserted when the monitored voltage is outside its overvoltage or undervoltage window (for TPS37044, SENSE1 or SENSE2), stays asserted during the reset timeout after returning in window, and requires an external pull-up resistor.
