    Milestone Semiconductor Inc.  GENERAL DESCRIPTION MST9611 is an Over-Voltage-Protection (OVP) and Over-Current-Protection (OCP) device. It can disconnect IN to OUT to protect load in case wrong input operating conditions are detected. The system is positive overvoltage protected up to 36V. The internal overvoltage thresholds (OVLO) is 6.1V and internal overcurrent thresholds (OCP) MST9611 also has internal over temperature protect(OTP) function and it can monitor chip temperature to protect the device. The device is packaged in advanced is 2.7A. Over Voltage and Over Current Protection IC  FEATURES Typical RON: 100mΩ NMOS @5V/1A Maximum Output Current: 2.5A. VIN Operating Range: 2.5V to 36V Internal Overvoltage Lockout : 6.1V Internal Overcurrent Lockout : 2.7A(MIN) Overvoltage-Protection Response Time： <500ns Startup Debounce Time: 16ms(TYP). Typical Output Power on Time: 16.5ms(TYP). Internal Thermal-Shutdown Protection ESD Protected: Human Body Model ： JESD22-A114(All pins)±2KV  APPLICATION GPS and Navigation Equipment Portable Media Devices, Laptop & MID SLR Digital Cameras Industrial Handheld Equipment and Enterprise full-Green Packaging (DFN4).

    Milestone Semiconductor Inc.  PIN ASSIGNMENT Over Voltage and Over Current Protection IC PIN 1 2、3 4 NAME IN GND OUT DISCRIPTION Input Voltage. Ground. Connect GND pins together for proper operation. Load Output.  BLOCK DIAGRAM  FUNCTIONAL DESCRIPTION feature a The OVP switch with overvoltage protection low 100mΩ (typical) on-resistance(RON) internal FET and protect low-voltage systems against voltage faults up to 36VDC. The internal overvoltage thresholds (OVLO) is 6.1V and internal overcurrent thresholds (OCP) is 2.7A. The internal FET turns off when the junction temperature exceeds +155ºC (TYP.). The device exits thermal shutdown after the junction temperature cools by 20ºC (TYP.). Page2-7 Rev.1.1 Mar-06-2018
    Milestone Semiconductor Inc. Input Capacitor Over Voltage and Over Current Protection IC To limit the voltage drop on the input supply caused by transient inrush current when the switch turns on into a discharged load capacitor or short-circuit, a capacitor 1μF or lager must be placed between the VIN and GND pins. Output Capacitor A 1μF or lager capacitor should be placed between the OUT and GND pins.  ABSOLUTE MAXIMUM RATINGS Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.
