3 Description
The TPS206x-Q1 power-distribution switch is
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.
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).
