TPS4045BD datasheet

 

Description :

The TPS204xB/TPS2055B power-distribution switches are intended for applications where heavy capacitive loads and short circuits are likely to be encountered. These devices incorporate 70-mΩ N-channel MOSFET power switches for power-distribution systems that require multiple power switches 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 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.

Features

1. 70-mΩ High-Side MOSFET
2. 250-mA Continuous Current
3. Thermal and Short-Circuit Protection
4. Accurate Current Limit (0.3 A min, 0.7 A max)
5. Operating Range: 2.7 V to 5.5 V
6. Undervoltage Lockout

Applications

1. Heavy Capacitive Loads
2. Short-Circuit Protections
