LM57TPWR 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 | input | Analog trip-point resistor sense input; one of two sense pins which selects the temperature at which TOVER and TOVER will assert via external resistor divider. |
| 3 | SENSE2 | input | Analog trip-point resistor sense input; one of two sense pins which selects the temperature at which TOVER and TOVER will assert via external resistor divider. |
| 4 | VDD | power_in | Power supply voltage input; recommended operating range from 2.4 V to 5.5 V. |
| 5 | TRIP TEST | input | Active-high digital test input; when low (default) VTEMP provides analog temperature sensor output, when high TOVER and TOVER outputs assert and VTEMP equals VTRIP. |
| 6 | TOVER | tri_state | Overtemperature switch output, active-low open-drain; asserted when measured temperature exceeds the trip point temperature or if TRIP TEST = 1, requires external pullup resistor. |
| 7 | TOVER | output | Overtemperature switch output, active-high push-pull; asserted when measured temperature exceeds the trip point temperature or if TRIP TEST = 1. |
| 8 | VTEMP | output | Analog temperature sensor output voltage; provides temperature-proportional voltage from -50°C to +150°C with accuracy of ±1.3°C or ±2.3°C depending on grade. |
