The TPS22810TDBVRQ1 is a single-channel load switch with adjustable rising time and rapid output discharge (QOD). This article mainly introduces Layout, Pinout, Datasheet and other detailed information about Texas Instruments TPS22810TDBVRQ1.
TPS22810TDBVRQ1
The TPS22810TDBVRQ1 is a single-channel load switch with adjustable rising time and rapid output discharge (QOD). The device has a thermal shutdown feature that protects it from high junction temperatures and ensures that the device's operation area is always safe. An N-channel MOSFET is used in the device, which can run between 2.7 and 18 V in input voltage. A maximum current of 2 A can be supported by the gadget. An on/off input that can connect directly with low-voltage control signals controls the switch.
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 TPS22810TDBVRQ1 is offered in a leaded SOT-23 packaging (DBV) that allows solder connections to be visually inspected. The gadget is designed to operate in a temperature range of –40°C to +105°C in free air.
The following figure is TPS22810TDBVRQ1 Pinout.
Pinout
| Pin Number | Pin Name | Description |
| 4 | CT | Switch slew rate control. Can be left floating |
| 3 | EN/UVLO | Active high switch control input and UVLO adjustment. Do not leave floating |
| 2 | GND | Device ground |
| 5 | QOD | Quick Output Discharge pin. This functionality can be enabled in one of three ways: • Placing an external resistor between VOUT and QOD • Tying QOD directly to VOUT and using the internal resistor value (RPD) • Disabling QOD by leaving pin floating |
| 1 | VIN | Switch input. Place ceramic bypass capacitor(s) between this pin and GND |
| 6 | VOUT | Switch output |

Functional Block Diagram
The following is TPS22810TDBVRQ1 Test Circuit.
Test Circuit
The TPS22810TDBVRQ1 Simplified Schematic is shown as follows.
Simplified Schematic
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.
