LM25069PMMX-2

Texas Instruments · Surge Protection Devices (SPDs) · VSSOP-10-0.5mm

LM25069PMMX-2 from Texas Instruments, in a VSSOP-10-0.5mm. 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	SENSE	input	Current sense input: the voltage across the current sense resistor (RS) is measured from VIN to this pin, and if it reaches 50mV the load current is limited and the fault timer activates.
2	VIN	power_in	Positive supply input; a small ceramic bypass capacitor close to this pin is recommended to suppress transients when the load current is switched off.
3	UVLO/EN	input	Under-voltage lockout and enable input: an external resistor divider from the system input sets the turn-on threshold, an internal 20 µA source gives hysteresis, the enable threshold is 1.17V, and the pin can be used for remote shutdown.
4	OVLO	input	Over-voltage lockout input: an external resistor divider from the system input sets the turn-off threshold, an internal 20 µA source gives hysteresis, and the disable threshold at the pin is 1.16V.
5	GND	power_in	Circuit ground.
6	TIMER	passive	Timing capacitor pin: the external capacitor sets the insertion time delay and the fault timeout period, and also sets the restart timing of the LM25069-2.
7	PWR	input	Power limit set: an external resistor on this pin, together with the current sense resistor (RS), sets the maximum power dissipation allowed in the external series pass MOSFET.
8	PGD	output	Power Good open-drain output: it is active (high) when the external MOSFET VDS decreases below 1.3V and switches low when VDS increases above 1.9V.
9	OUT	input	Output feedback: connect to the output rail (external MOSFET source), used internally to determine MOSFET VDS for power limiting and to control the PGD indicator.
10	GATE	output	Gate drive output: connect to the external MOSFET gate; this pin's voltage is limited to 19.5V above ground.
