DESCRIPTION
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.
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.
