AOZ13937DI-03/-04 ECPower™ 32 V 20 mΩ Smart Protection Switch Ideal Diode True Reverse Current Blocking General Description AOZ13937DI is 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. AOZ13937DI is the ideal solution for multi-port Type-C PD current application. The Ideal Diode True Reverse Current Blocking (IDTRCB) feature prevents VIN to rise due to reverse current flow from VOUT under all conditions.
