TRIPLE CURRENT-LIMITED POWER-DISTRIBUTION SWITCHES

The TPS2047 and TPS2057 triple power-distribution switches are intended for applications where heavy capacitive loads and short circuits are likely. These devices incorporate in single packages three 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 TPS2047 and TPS2057 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 TPS2047 and TPS2057 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
