AOZ13937DI-04
ECPower™ Type C Protection Switch
Status: Full Production
AOZ13937DI is a protection switch intended for applications that require reverse current protection. The input operating voltage range is from 3.4 V to 32 V, and both VIN and VOUT terminals are rated at 39 V absolute maximum. The power switch is capable for 20 A surge current for 10ms. AOZ13937DI provides under-voltage lockout, over-voltage, reverse-current, and over-temperature protection. The FLTB pin flags thermal shutdown and over-voltage faults.
