LTC2950ITS8-1#TRMPBF

Analog Devices · Supervisor And Reset ICs · TSOT-23-8

LTC2950ITS8-1#TRMPBF from Analog Devices, 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 VIN power_in Power supply input with an operating range of 2.7V to 26.4V.
2 PB input Pushbutton input (switch to ground) with an internal 100k pull-up to a 1.9V bias, which can be pulled up externally to 26.4V without extra current draw.
3 ONT passive Additional adjustable turn-on time input; a capacitor to ground sets the extra PB debounce time beyond the internal 32ms default, and floating the pin gives 32ms.
4 GND power_in Device ground.
5 INT output Open-drain interrupt output that is pulled low after a pushbutton turn-off event to signal the µP to power down, and that releases the enable output when KILL is driven low (or immediately if tied to KILL).
6 EN/EN output Open-drain enable output (high-true EN on the LTC2950-1) that is asserted high after a valid PB turn-on and released low if KILL is not driven high within 512ms, KILL is driven low in normal operation, or a second valid PB event occurs; operating range is 0V to 10V and a pull-up is required when the load has none.
7 OFFT passive Additional adjustable turn-off time input; a capacitor to ground sets the extra PB hold time before power-down begins, and floating the pin gives the 32ms default.
8 KILL input KILL input; forcing it low releases the enable output, it has an accurate 0.6V threshold, it is blanked for 512ms after turn-on, and it can be used as a voltage monitor input.
