Description

The DML3020UDC is a protection switch intended for applications that require reverse-current protection. The input operating voltage range is from 3.4V to 22V, and both VIN and VOUT terminals are rated at 28V absolute maximum. The power switch is capable for 15A surge current for 10ms. The DML3020UDC provides undervoltage lockout, overvoltage and overtemperature protection. The FLTB pin flags thermal shutdown, overvoltage and reverse-current faults.
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 offers industry’s lowest ON-resistance and highest SOA to safely handle high current and wide range of output capacitances on VOUT.

The DML3020UDC is housed in the low-profile and space-saving VDFN3030-12 (Type C) package which is manufactured with environmental-friendly material.
