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
