TPS2051B-Q1 汽车类单路限流配电开关
TPS2051B-Q1 描述
The TPS204xB/TPS205xB power-distribution switches are intended for applications where heavy capacitive loads and short circuits are likely to be encountered. These devices incorporate
70-m 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.
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
