TPS22810DBVR On-Resistance Load Switch: Circuit, Pinout, and Datasheet

The TPS22810DBVR is a single-channel load switch with adjustable rising time and built-in quick output discharge  (QOD). Furthermore, the gadget has a thermal shutdown to safeguard it from high junction temperatures. As a result, the device's safe functioning region is essentially ensured. The device features an N-channel MOSFET that can operate between 2.7 to 18 V in input voltage. A maximum current of 2 A can be supported by the SOT23-5 (DBV) package. The  WSON  (DRV) package can handle up to 3 A of current. The switch is operated via an on/off input that can interface with low-voltage control signals directly.

The device's programmable rise time minimizes inrush current generated by large bulk load capacitances, lowering or eliminating power supply droop. Undervoltage lock-out turns off the device if the VIN voltage falls below a certain threshold, preventing downstream circuitry from being harmed by a voltage that is lower than intended. To offer design freedom for power down, the programmable QOD pin controls the device's fall time.

The TPS22810DBVR is offered in two packages: a leaded SOT-23 package (DBV) that enables for visual inspection of solder connections, and a  WSON package (DRV). The gadget is designed to operate in a temperature range of –40°C to +105°C in free air.

Layout Guidelines

1. To accommodate high current, VIN and VOUT traces must be as short and wide as possible.

2. Ceramic bypass capacitors with low ESR must be used to connect the VIN pin to ground. 1-F ceramic with X5R or X7R dielectric is a standard recommended bypass capacitance. This capacitor should be as close as feasible to the device pins.
