Description

The TPS20xxB power-distribution switches are

intended for applications where heavy capacitive

loads and short circuits are likely to be encountered.

These devices incorporates 70mΩ 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 2.7V.

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

1A (typical).
