Product Overview

The TPS2051BDBVR is a single current-limited 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 that require multiple power switches. 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 over-current (OCx) logic output low.
  • Thermal and short-circuit protection
  • Under-voltage lockout
  • Deglitched fault report (OC)
  • No OC glitch during power up
  • Accurate current limit (0.75A minimum, 1.25A maximum)
  • 70mΩ High-side MOSFET
  • 500mA Continuous current
  • 0.6ms Typical rise time
Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
