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.
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.
It incorporates an
undervoltage lockout feature that shuts down the LTC1772 when the input voltage falls below 2.0V.
Protection features include output overvoltage and overcurrent,
undervoltage lockout and overtemperature.
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.
