TPS386596 具有手动复位输入的四路电压监控器
TPS386596 描述
The TPS386596L33 monitors four power rails and asserts the RESET signal when any of the SENSE inputs drop below their respective thresholds. SVS-1 can be used to monitor a 3.3V nominal power supply with no external components required. SVS-2, SVS-3, and SVS-4 are adjustable using external resistors and can be used to monitor any power supply voltage higher than 0.4V. All SENSE inputs have a threshold accuracy of 0.25% (typical). The TPS386596L33 also has an active low Manual Reset (MR) that can be used to assert the RESET signal as desired by the application. The open drain, active low RESEToutput de-asserts using a fixed 50ms delay.
The TPS386596L33 has a low quiescent current of 7µA typical and is available in a space saving 8-pin MSOP package.
