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 in an 8-pin dual in-line package (DIP) and operates over a junction temperature range of –40°C to 125°C.
