TPS2311 具有内部相关通道电路中断功能和电源良好报告功能的 3-13V 双路热插拔 IC,工作态高电平启用

TPS2311 描述

The TPS2310 and TPS2311 are dual-channel hot-swap controllers that use external N-channel MOSFETs as high-side switches in power applications. Features of these devices, such as overcurrent protection (OCP), inrush current control, output-power status reporting, and the ability to discriminate between load transients and faults, are critical requirements for hot-swap applications. The TPS2310/11 devices incorporate undervoltage lockout (UVLO) and power-good (PG) reporting to ensure the device is off at start-up and confirm the status of the output voltage rails during operation. Each internal charge pump, capable of driving multiple MOSFETs, provides enough gate-drive voltage to fully enhance the N-channel MOSFETs. The charge pumps control both the rise times and fall times (dv/dt) of the MOSFETs, reducing power transients during power up/down.
