QUAD CURRENT-LIMITED POWER-DISTRIBUTION SWITCHESThe TPS2048 and TPS2058 quad power-distribution switches are intended for applications where heavy
capacitive loads and short circuits are likely. These devices incorporate in single packages four 135-m
N-Channel MOSFET high-side Power Switches for power-distribution systems that require multiple power
switches. Each Switch is controlled by a Logic enable compatible with 5-V and 3-V Logic Gate drive is provided
by an internal Charge Pump that controls the power-switch rise times and fall times to minimize current surges
during switching. The Charge Pump requiring no external components, 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 TPS2048 and TPS2058 limit
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 in overcurrent 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 TPS2048 and TPS2058 are designed to limit at 0.44-A load. These power-distribution switches are
available in 16-pin small-outline integrated circuit (SOIC) packages and operate over an ambient temperature
range of 40C to 85C By Texas Instruments
