description
The TPS202x family of power distribution switches is intended for applications where heavy capacitive loads and
short circuits are likely to be encountered. These devices are 50-mΩ N-channel MOSFET high-side power switches.
The switch is controlled by a logic enable compatible with 5-V logic and 3-V logic. Gate drive is provided by an
internal charge pump designed to control the power-switch rise times and fall times to minimize current surges
during switching. The charge pump requires no external components and allows operation from supplies as low as
2.7 V.
When the output load exceeds the current-limit threshold or a short is present, the TPS202x limits the output current
to a safe level by switching into a constant-current mode, pulling the overcurrent (OC) logic output low. When
continuous heavy overloads and short circuits increase the power dissipation in the switch, causing the junction
temperature to rise, a thermal protection circuit shuts off the switch to prevent damage. Recovery from a thermal
shutdown is automatic once the device has cooled sufficiently. Internal circuitry ensures the switch remains off until
valid input voltage is present.
The TPS202x devices differ only in short-circuit current threshold. The TPS2020 limits at 0.3-A load, the TPS2021
at 0.9-A load, the TPS2022 at 1.5-A load, the TPS2023 at 2.2-A load, and the TPS2024 at 3-A load (see Available
Options). The TPS202x is available in an 8-pin small-outline integrated-circuit (SOIC) package and operates over
a junction temperature range of − 40°C to 125°C.
