TI TPS2065QDGNRQ1

The TPS2062/5-Q1 power distribution switch is primarily intended for applications where large capacitive loads and short-circuit conditions are likely to occur. This device incorporates a 70mΩ N-channel MOSFET power switch for power distribution systems where multiple power switches are required in a single package. Each switch is controlled by a logic enable input. Gate drive is provided by an internal charge pump designed to control the power switch rise and fall times to significantly reduce inrush current during switching. The charge pump requires no external components and operates at supply voltages as low as 2.7V.

When the output load exceeds the current-limiting threshold or a short circuit occurs, the device limits the output current to a safe level by switching to a constant current mode and pulling the overcurrent indicator (OCx̄) low to a logic output low level. When sustained heavy overloads and short circuits increase power dissipation within the switch, causing the junction temperature to rise, a thermal protection circuit shuts down the switch to prevent device damage. Once the device has cooled sufficiently, it automatically recovers from thermal shutdown. Internal circuitry ensures the switch remains off until a valid input voltage is present. This power distribution switch is designed to set the typical current limit value at 1.5A.
