Two boundaries in Figures 7 and 8 reveal the undervoltage lockout (ULVO) specifications which must be used for the gate driver.
* Internal protection features, such as thermal shutdown and undervoltage lockout.
The ISL820xM modules offer an array of protection features, including input undervoltage lockout (UVLO), over-temperature, overcurrent and short-circuit with hiccup mode, overvoltage, and negative overcurrent to guarantee safe operation under abnormal operating conditions.
Features include remote ON/OFF overcurrent protection and undervoltage lockout. The units are provided in an industry standard quarter brick package.
* Input undervoltage lockout, output overcurrent protection, output overvoltage protection, overtemperature protection, remote output voltage sense and output voltage trim using industry-standard trim equations.
Additional features include output short-circuit protection, 116uAno load operating quiescent current, accurate enable and undervoltage lockout with hysteresis, internal soft stmt and loop compensation, along with output diode temperature compensation.
The AP91352 provides undervoltage lockout, overvoltage clamp, thermal shutdown and reverse-current protection for downstream power components to prevent damage and premature component failure.
It incorporates an undervoltage lockout feature that shuts down the LTC1772 when the input voltage falls below 2.0V.
An accurate 1.6V EN/UVLO pin threshold allows undervoltage lockout (UVLO) to be programmed for optimal system performance.
Protection features include output overvoltage and overcurrent, undervoltage lockout and overtemperature.
Protection features for the devices include undervoltage lockout (UVLO), shoot-through protection, and a thermal warning feature that alerts the system in case of an excessive junction temperature.
Features include average current-mode or voltage-mode control, soft-start, [V.sub.cc] undervoltage lockout with hysteresis, undervoltage, overvoltage and overpower protection and thermal shutdown with hysteresis.
