Overview
Description
MAX706CSA is a Maxim Integrated (now Analog Devices) MAX706-series microprocessor supervisory/reset IC. It monitors the supply voltage and generates a guaranteed reset signal to a microcontroller or digital logic on power-up or brown-out, ensuring proper startup and operation. The CSA suffix identifies a specific package/temperature variant of the device; exact reset thresholds, timing, and features vary by variant.
Typical features (depending on the variant) include:
- Defined reset output (active low or high) with debounce
- Power-on reset delay to ensure stable startup
- Low quiescent current
- Optional features such as a watchdog timer and manual reset input (present on some variants)
- Wide common supply range compatible with many MCUs
Common applications: MCU/CPU reset supervision, power-on/brown-out protection in embedded systems, and safe startup sequencing in battery-powered devices.
For precise electrical characteristics (thresholds, reset timeout, output type, package), refer to the MAX706CSA datasheet.
