SGM836-3.3Q Datasheet | SG Micro

DESCRIPTION The SGM836x Q family can monitor system voltages from 0.4V to 5V. When the detection voltage falls below the preset threshold (VITL) or the manual reset (n MR) pin is driven low, the open-drain n RESET output is asserted. After the detection voltage and n MR voltage return higher than their respective thresholds, the n RESET output remains low within the user-adjustable delay time. The SGM836x Q uses a precision reference to achieve 2.2% threshold accuracy under the temperature range of -40℃ to +125℃. The fixed reset timeout period can be set to 20ms by leaving the CT pin open and can be set to 300ms by connecting the CT pin to VDD through a resistor. The programmable reset timeout period can be set from 1.1ms to 10s through an external capacitor connected to the CT pin. Low quiescent current makes the SGM836x Q very suitable for battery-powered applications. The device is AEC-Q100 qualified (Automotive Electronics Council (AEC) standard Q100 Grade 1) and it is suitable for automotive applications. The SGM836x Q is available in Green SOT-23-6 and TDFN-2×2-6GL packages.
