LM57FPWR from Texas Instruments, in a TSSOP-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 | GND | power_in | Power supply ground. |
| 2 | SENSE1 | passive | Trip-point resistor sense pin; one of two that selects the temperature at which TOVER and TOVER assert, with pin voltages limited to -0.3 V to VDD + 0.3 V. |
| 3 | SENSE2 | passive | Trip-point resistor sense pin; one of two that selects the temperature at which TOVER and TOVER assert, with pin voltages limited to -0.3 V to VDD + 0.3 V. |
| 4 | VDD | power_in | Power supply voltage, specified from 2.4 V to 5.5 V, with absolute maximum of 6 V. |
| 5 | TRIP TEST | input | Active-high test input: when low (default) VTEMP gives the temperature sensor voltage, and when high TOVER and TOVER are asserted and VTEMP outputs the trip voltage VTRIP; tie to ground if not used. |
| 6 | TOVER | output | Active-low open-drain overtemperature switch output, asserted when the measured temperature exceeds the trip point or when TRIP TEST = 1, requires an external pullup, may be left open if not used, and is rated to 6 V absolute maximum. |
| 7 | TOVER | output | Active-high push-pull overtemperature switch output, asserted when the measured temperature exceeds the trip point or when TRIP TEST = 1, may be left open if not used, and is rated to 6 V absolute maximum. |
| 8 | VTEMP | output | Analog temperature sensor output voltage (VTS when TRIP TEST = 0, VTRIP when TRIP TEST = 1), with voltage limited to -0.3 V to VDD + 0.3 V and may be left open if not used. |
