description
The TPS201xA family of power distribution switches is intended for applications where heavy capacitive loads
and short circuits are likely to be encountered. These devices are 50-m
N-channel MOSFET high-side power
switches. The switch is controlled by a logic enable compatible with 5-V logic and 3-V logic. 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 TPS201xA limits the output
current to a safe level by switching into a constant-current mode. 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 the switch remains off until valid input voltage is
present.
The TPS201xA devices differ only in short-circuit current threshold. The TPS2010A limits at 0.3-A load, the
TPS2011 at 0.9-A load, the TPS2012A at 1.5-A load, and the TPS2013A at 2.2-A load (see Available Options).
The TPS201xA is available in an 8-pin small-outline integrated-circuit (SOIC) package and in a 14-pin
thin-shrink small-outline package (TSSOP) and operates over a junction temperature range of –40
°
C to 125
