IPS5551T

FULLY PROTECTED HIGH SIDE POWER MOSFET SWITCH

Description

The IPS5551T is a fully protected three terminal high side

switch with built-in short-circuit, over-temperature, ESD

protection, inductive load capability. The input signal is

referenced to Vcc. When the input voltage Vcc - Vin is

higher than the specified threshold, the output power

MOSFET is turned on. When the Vcc - Vin is lower than the

specified Vil threshold, the output MOSFET is turned off.

Input noise immunity is improved by an hysterisis. When

the input is left floating, an internal current source pulls it up

to Vcc. The over-current protection latches off the high side

switch if the output current exceeds the specified Isd. The

over-temperature protection latches off the switch if the

junction temperature exceeds the specified value Tsd. The

device is reset by opening the input pin high.
