LTC2955CDDB-1#TRPBF

Analog Devices · Monitors & Reset Circuits · DFN-10-EP(2x3)

LTC2955CDDB-1#TRPBF from Analog Devices, in a DFN-10-EP(2x3). 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 INT output Open-drain interrupt output, pulled low on a turn-off command from the pushbutton or ON pin, with a minimum pulse width of 32ms extendable through TMR, and rated -0.3V to 6V.
2 PGD output ON status output that goes high (1.5V to 5.5V, 2µA pull-up) when the ON pin is above its 0.8V threshold, telling the system whether turn-on came from ON or PB; leave open if unused.
3 EN output Active-high enable output (LTC2955-1) asserted when the pushbutton is pressed or ON goes high, with a 2µA pull-up and a high level that follows the internal LDO (1.5V to 5.5V), for connection to a regulator RUN or SHUTDOWN pin.
4 VIN power_in Power supply input with a 1.5V to 36V operating range (40V absolute maximum); for >20V applications connect through a 1k resistor and bypass to GND with a 10nF low-ESR capacitor.
5 PB input Active-low pushbutton input with a 900k pull-up to an internal LDO, tolerant of ±36V, connected between the pushbutton and GND; may be left open if unused.
6 GND power_in Device ground.
7 SEL input Mode select input: GND blocks the ON falling edge from causing turn-off, VIN allows both ON rising and falling edges to turn the system on and off; do not leave open.
8 TMR passive Timer pin where a capacitor to ground adds 5.2 seconds/µF beyond the default 64ms turn-off debounce time; grounding the pin disables forced power-down by pushbutton press.
9 KILL input Kill input with a 0.8V threshold where a low releases the enable output; tie to the system supply or an external 1.2V to 5V if unused (absolute maximum 6V).
10 ON input Monitor input with a 0.8V rising threshold connected to a resistive divider for automatic system turn-on (and turn-off when SEL is high); tie to GND if unused.
11 EP passive Exposed pad (DFN only); leave open or connect to device ground.
