Operating Range: 2.7 V to 5.5 V  
0.6-ms Typical Rise Time  
The TPS206x-1 power-distribution switches are  
intended for applications where heavy capacitive  
loads and short-circuits are likely to be encountered.  
This device incorporates 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.

APPLICATIONS  
•
Heavy Capacitive Loads  
•
Short-Circuit Protections  
These switches provide a discharge function that  
provides a controlled discharge of the output voltage  
stored on the output capacitor.  
When the output load exceeds the current-limit threshold or a short is present, the device limits the output  
current to a safe level by switching into a constant-current mode, pulling the overcurrent (OCx) 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 that the switch  
remains off until valid input voltage is present. This power-distribution switch is designed to set current limit at  
1.5 A typically.
