Single-/Dual-/Triple-Voltage μP Supervisor Circuits With Independent Watchdog Output

The MAX6730A MAX6735A single-/dual-/triple-voltage Microprocessor (P) supervisors feature a watchdog Timer and manual reset capability. The MAX6730A MAX6735A offer factory-set reset thresholds for monitoring voltages from +0.9V to +5V and an adjustable reset input for monitoring voltages down to +0.63V. The combination of these features significantly i 4de mproves system reliability and accuracy when compared to separate ICs or Discrete components.
The active-low reset output asserts and remains asserted for the reset timeout period after all the monitored voltages exceed their respective thresholds. Multiple factory-set reset threshold combinations reduce the number of external components required. The MAX6730A MAX6731A monitor a single fixed voltage, the MAX6732A MAX6733A monitor two fixed voltages, and the MAX6734A MAX6735A monitor two fixed voltages and one adjustable voltage. All devices are offered with six minimum reset timeout periods ranging from 1.1ms to 1120ms.
The MAX6730A MAX6735A feature a watchdog Timer with an independent watchdog output. The watchdog Timer prevents system lockup during code execution errors. A watchdog startup delay of 54s after reset asserts allows system initialization during power-up. The watchdog operates in normal mode with a 1.68s delay after initialization. The MAX6730A MAX6732A MAX6734A provide an active-low, open-drain watchdog output. The MAX6731A MAX6733A MAX6735A provide an active-low, push-pull watchdog output.
Other features include a manual reset input MAX6730A MAX6731A MAX6734A MAX6735A and p 4fb ush-pull reset output MAX6731A MAX6733A MAX6735A or open-drain reset output MAX6730A MAX6732A MAX6734A . The MAX6730A MAX6733A are offered in a tiny 6-pin SOT23 package. The MAX6734A MAX6735A are offered in an 8-pin, space-saving SOT23 package. All devices are fully specified over the extended -40C to +125C temperature range.
