Texas Instruments · Monitors & Reset Circuits · TSSOP-24

LM96080CIMTX from Texas Instruments, in a TSSOP-24. 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_IN input Active-low interrupt input that propagates the INT_IN signal to the INT output of the LM96080.
2 SDA bidirectional Serial bus bidirectional data pin with NMOS open-drain output.
3 SCL input Serial bus clock input.
4 FAN1 input Fan tachometer input 1.
5 FAN2 input Fan tachometer input 2.
6 BTI input Board Temperature Interrupt input driven by the O.S. outputs of additional temperature sensors such as LM75, with an internal 10 kΩ pull-up.
7 GPI (CI) bidirectional General purpose input usable as an additional active-high interrupt input or as an input from an external circuit latching a Chassis Intrusion event.
8 GND power_in Ground, internally connected to all of the digital circuitry.
9 V+ power_in +3.0V to +5.5V power supply, bypassed with 10 μF (electrolytic or tantalum) in parallel with 0.1 μF (ceramic) capacitors.
10 INT output Interrupt output, non-maskable active-high PMOS open-drain or active-low NMOS open-drain interrupt request, active whenever INT_IN, BTI, or GPI interrupts.
11 GPO output General purpose active-low NMOS open-drain output intended to drive an external power PMOS for software power control or to control power to a cooling fan.
12 NTEST_IN/RESET_IN input Active-low input that enables NAND Tree board-level connectivity testing, and the LM96080 resets to its power-on state whenever NAND Tree connectivity is enabled.
13 RST_OUT/OS output NMOS open-drain output where RST_OUT provides a master reset to connected devices and OS is dedicated to the temperature reading WATCHDOG.
14 GNDA power_in Analog ground, internally connected to all analog circuitry and the reference for all analog inputs; must be taken to a low-noise analog ground plane.
15 IN6 input Analog input with 0V to 2.56V full-scale range.
16 IN5 input Analog input with 0V to 2.56V full-scale range.
17 IN4 input Analog input with 0V to 2.56V full-scale range.
18 IN3 input Analog input with 0V to 2.56V full-scale range.
19 IN2 input Analog input with 0V to 2.56V full-scale range.
20 IN1 input Analog input with 0V to 2.56V full-scale range.
21 IN0 input Analog input with 0V to 2.56V full-scale range.
22 A0/NTEST_OUT bidirectional Lowest order bit of the serial bus address, which also functions as an output during a NAND Tree test.
23 A1 input One of the two highest order bits of the serial bus address.
24 A2 input One of the two highest order bits of the serial bus address.
