Manufacturer:BOURNS Description:GAT: Gate drive for an external N-channel protection power MOSFET. When either input supply is above the UV threshold and both are below the OV threshold, gate drive is enabled and the device begins charging the external capacitor connected to RAMP. RAMP develops the reference voltage at the non-inverting input of the internal LCA. The inverting input is connected to the current sense node, SENSE. The LCA acts to slew the pass FET gate to force the SENSE voltage to track the reference. The reference is internally clamped to 42 mV, so the maximum current that can be sourced to the load is determined by the sense resistor value as IMAX 42 mV/RSENSE. Once the load voltage has ramped up to the input dc potential and current demand drops off, the LCA drives GAT 14 V above SOURCE to fully enhance the pass FET, completing the low-impedance supply return path for the load. |
