Overview
The NJW4832 is a single-channel high-side switch capable of supplying 0.2A output current. A P-channel MOSFET is integrated on-chip, along with comprehensive fault protection circuits for overvoltage, overcurrent and thermal shutdown. It can be directly controlled by 3V logic signals from MCU or DSP, eliminating the need for level shifters when operating with 3V microcontrollers. This device is ideal for integrated output circuits of optical, pressure and flow sensors. Two FLT fault logic modes are available: Active-high and Active-low.
