TPS2043 Datasheet | Texas Instruments

description GND2 5 IN2 6 12 OC3 11 OUT3 The TPS2043 and TPS2053 triple power EN3 7 10 NC distribution switches are intended for applications NC 8 9 NC where heavy capacitive loads and short circuits are likely to be encountered. The TPS2043 and - No internal connection the TPS2053 incorporate in single packages three 135-mΩ N-channel MOSFET high-side power switches for power-distribution systems that require multiple power switches. Each switch is controlled by a logic enable that is patible with 5-V logic 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 ponents, 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 TPS2043 and TPS2053 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 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 TPS2043 and TPS2053 are designed to limit at 0.9-A load. These power distribution switches are available in a 16-pin small-outline integrated circuit (SOIC) package and operate over an ambient temperature range of - 40°C to 85°C.
