PIN FUNCTIONS TMR:
Fault Timer Input. Connect a capacitor between this
UV:
Undervoltage Comparator Input. When the UV pin pin and ground to set the times for fault warning, fault falls below its 1.25V threshold, the HGATE pin is pulled turn-off, and cool down periods. Either voltage regulation down with a 1mA current. When the UV pin rises above or current regulation starts pulling up the TMR pin. The 1.25V plus the hysteresis, the HGATE pin is pulled up by current charging up this pin during the fault conditions the internal charge pump. For LTC4364-1, after HGATE increases with the voltage difference between VCC and OUT is latched off, pulling the UV pin below 0.6V resets the pins (see Applications Information). When TMR reaches latch and allows HGATE to retry. If unused, connect to 1.25V, the FLT pin pulls low to indicate the detection of a the SHDN pin. fault condition. If the condition persists, the pass device

Positive Supply Voltage Input. The positive supply input ranges from 4V to 80V for normal operation. It can threshold of 1.35V. As soon as the fault condition disap- also be pulled below ground potential by up to 40V during pears, a cool down interval commences while the TMR a reverse battery condition, without damaging the part. pin cycles 32 times between 0.15V and 1.35V with 2μA Shutting down the LTC4364 by pulling the SHDN pin to charge and discharge currents. When TMR crosses 0.15V ground reduces the V the 32nd time, the HGATE pin is allowed to pull high turn- CC current to 10μA. ing the pass device back on if the OV pin voltage is below its threshold for the LTC4364-2 version.
