During above condition, driver will be shutdown if over voltage state occurs (VCC>VOVP1) for continual a blanking time. The first OVP function will not inactive after soft-start phase. The second OVP will shutdown the switching of the power MOSFET whenever VCC>VOVP2. The first OVP case as followed FIG.7. The test circuit as followed FIG. 9.

LINEAR INTEGRATED CIRCUIT FIG.8 OLP test circuit FIG.9 OVP test circuit OTP OTP will shut down driver when junction temperature TJ>T (THR) for continual a blanking time. (7) Driver Output Section The driver-stage drives the gate of the MOSFET and is optimized to minimize EMI and to provide high circuit efficiency. This is done by reducing the switch on slope when reaching the MOSFET threshold. This is achieved by a slope control of the rising edge at the driver’s output. The output driver is clamped by an internal 15V Zener diode in order to protect power MOSFET transistors against undesirable gate over voltage. (8) Inside power switch MOS transistor Specific power MOS transistor parameter is as “POWER MOS TRANSISTOR SECTION” in electrical characteristics table.
