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. |
