4-channel voltage monitoring in a 10-pin MSOP
The MAX6709KUB+ is a multi-voltage supervisor from Analog Devices that monitors four independent supply voltages, issuing a reset when any monitored rail falls below its threshold. The factory-set thresholds are 1.58 V and 2.93 V on two channels, with the remaining two channels adjustable via external resistor dividers — covering common core and I/O rails in a mixed-voltage design. Housed in a 10-pin TFSOP/MSOP package (3.00 mm width), it fits tight board layouts where a single supervisor replaces multiple discrete reset ICs.
Reset output and timeout behavior
Reset timeout is under 1 ms minimum, meaning the output de-asserts quickly after the supply recovers, suitable for processors that require a clean power-good handshake within a tight window. The open-drain output allows wire-OR connection with other supervisors or a pull-up to a different logic voltage, giving flexibility in mixed-voltage systems.
Temperature grade and operating range
The supplier device package is 10-uMAX/uSOP — a standard footprint shared with other Maxim/Analog Devices supervisors, easing second-source or alternate BOM placement.
Active production and compliance
Fully ROHS3 compliant, it meets current European and global environmental regulations for lead-free assembly.
