UCC2946TPWRQ1

Texas Instruments · Supervisor And Reset ICs · TSSOP-8

UCC2946TPWRQ1 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 Ground reference for the device.
2 RTH input Input that compares its voltage to an internal 1.25-V reference for programming the reset threshold using external resistors.
3 RES output Output that is high only if the voltage on RTH has risen above 1.235 V and remains low for the reset period.
4 RP input Input pin that allows the user to program the reset period by adjusting an external capacitor.
5 WDO output Output that is asserted low if the WDI pin is not toggled or strobed within the watchdog period.
6 WP input Input pin that allows the user to program the watchdog period by adjusting an external capacitor.
7 WDI input Input to the watchdog timer that must be toggled within the watchdog period to prevent WDO assertion.
8 VDD power_in Supply voltage input for the device, operating range 2.1 V to 5.5 V.
