SGM852 Dual Adjustable Voltage Detector with Reset and Gate Driver Outputs GENERAL DESCRIPTION The SGM852 is a dual adjustable voltage detector with reset and gate driver outputs. Two adjustable sense inputs can monitor a wide voltage range through external resistor dividers. The device has internal sequence timing. The delay time of two outputs can be programmed by their respective external capacitors. The gate driver output is implemented for external N-MOSFET by a charge pump circuit. Two options are available. When both VSEN1 and VSEN2 voltages exceed the internal fixed rising threshold voltage in SGM852A, or VSEN1 voltage exceeds the internal fixed rising threshold and VSEN2 voltage falls below the internal fixed falling threshold in SGM852B, both internal parators output high, the reset output (n RESET) asserts high after a propagation delay and a capacitor charge set-time delay. And if either of the parators outputs low, n RESET asserts low. The SGM852 is available in a Green TDFN-3×3-10L package. It operates over a junction temperature range of -40℃ to +125℃.
