TPS2065DGNR-1

限流配电开关 CURRENT-LIMITED, POWER-DISTRIBUTION SWITCHES

DESCRIPON

The TPS206x-1 power-distribution switches are intended for applications where heavy capacitive

loads and short-circuits are likely to be encountered. This device incorporates 70-mΩ N-channel MOSFET power switches for power-distribution systems that require multiple power switches in a single package. 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 2.7 V.
