TPS386040 具有可编程延迟和看门狗定时器的四路电源电压监控器

TPS386040 描述

The TPS3860x0 family of voltage supervisors can monitor four power rails that are greater than 0.4V and one power rail less than 0.4V (including negative voltage) with a 0.25% (typical) threshold accuracy. Each of the four supervisory circuits (SVS-n) assert a RESETn or RESETn output signal when the SENSEm input voltage drops below the programmed threshold. With external resistors, the threshold of each SVS-n can be programmed (where n = 1, 2, 3, 4 and m = 1, 2, 3, 4L, 4H). Each SVS-n has a programmable delay before releasing RESETn or RESETn, and the delay time can be set from 1.4ms to 10s through the CTn pin connection. Only SVS-1 has an active-low manual reset (MR) input; a logic-low input to MR asserts RESET1 or RESET1
