Product Overview

The TPS2051BDGNR is a Power Distribution Switch intended for applications where heavy capacitive loads and short circuits are likely to be encountered. This device incorporates 70mΩ N-channel MOSFET power switches for power-distribution systems. 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.
  • 500mA Continuous current
  • 0.6ms Typical rise time
  • Undervoltage lockout
  • Deglitched fault report (OC)
  • No OC glitch during power up
