AOZ13937DI-01
AOZ13937DI-01 is Smart Protection Switch manufactured by Alpha & Omega Semiconductors.
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 10 ms. 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.
An internal soft-start circuit controls inrush current due to highly capacitive loads and the slew rate can be adjusted using an external capacitor. The integrated back-to-back MOSFET offer industry’s lowest ON resistance and highest SOA to safely handle high current and wide range of output capacitances on VOUT.
