Single-channel supervisor for 5V rail monitoring
The MAX791CUE+ is a single-channel Simple Reset/Power-On Reset supervisor from Analog Devices, packaged in a 16-TSSOP with a 4.40mm width body.
140ms reset timeout and commercial temperature range
The reset timeout is 140ms minimum — long enough for the monitored 5V rail to settle after power-up or a brownout event, preventing the processor from starting before the supply is stable. The 4.65V threshold sits at roughly 93% of a nominal 5V rail, giving early warning before the rail drops into the undefined logic region. The 16-TSSOP package with 0.65mm pitch requires a standard surface-mount assembly process and a 4-layer board if the designer wants a solid ground plane under the package.
