MAX8216CSD+

The MAX8216CSD+ from Analog Devices (Maxim Integrated) is a versatile multi-voltage supervisor IC designed for robust power supply monitoring in microprocessor-based systems. This device features four dedicated comparators for monitoring ±5V and ±15V supplies, along with a fifth auxiliary comparator for monitoring any desired voltage, making it suitable for complex power management scenarios.

Key electrical characteristics include a wide supply voltage range of 2.7V to 11V and a maximum supply current of 250µA. The dedicated 5V comparator boasts ±1.25% accuracy, while the ±5V, ±12V, ±15V comparators offer ±1.5% accuracy. An internal 1.24V reference with ±1% initial accuracy is integrated, simplifying external component requirements. The device includes built-in hysteresis and provides independent open-drain outputs.

Packaged in a 14-SOIC (0.154", 3.90mm Width) surface-mount package, the MAX8216CSD+ operates within a temperature range of 0°C to 70°C (TA). Its typical propagation delay for reset is 20µs. This supervisor is well-suited for applications requiring overvoltage/undervoltage detection, industrial controllers, mobile radios, and portable instruments.

This supervisor is designed for applications requiring precise voltage monitoring and reliable reset signals. The combination of dedicated and auxiliary comparators allows for flexible configuration in systems with multiple voltage rails. Its surface-mount package and operating temperature range make it suitable for a wide array of industrial and portable electronic designs.
