Description
The MP591C3 is a fully integrated, compact hot-swap protection device with back-to-back FETs. It contains a hot-swap controller and two high-side back-to-back power MOSFETs (HS-FETs), which allow it to operate as a standalone device. The device can achieve up to 16A of continuous output current (IOUT).
The device limits the backplane voltage drop by limiting the inrush current to the load while a circuit card is inserted into a live backplane power source. It also provides reverse-current blocking, which prevents current from flowing from the output (VOUT) to the input (VIN). The MP591C3 limits the internal MOSFET current (IFET) by controlling the gate voltage (VGATE) via the current limit (ILIMIT) reference input and soft-start (SS) ramp.
The MP591C3 provides many features to simplify system design, such as an integrated current mirror to monitor IOUT and integrated on-die temperature-sensing. This eliminates the need for an external current-sense (CS) power resistor, power MOSFET, and temperature-sense device.
Rich fault protections include VIN over-voltage protection (OVP), IOUT over-current protection (OCP), short-circuit protection (SCP), and over-temperature protection (OTP). The fault status can be indicated with the fault report output (FLTB).
The MP591C3 is available in a TLGA-25 (4mmx4mm) package.
