Maxim Integrated MAX6398ATT+T Voltage Supervisor IC

The Maxim Integrated MAX6398ATT+T is a compact, highly efficient voltage supervisor IC designed to monitor power supplies in digital systems. It provides excellent circuit reliability and low power consumption, making it an ideal choice for portable and battery-powered applications. The MAX6398ATT+T ensures that microprocessors (µPs), microcontrollers (MCUs), and other voltage-sensitive components operate within their specified voltage ranges, enhancing system stability and safety.

This voltage supervisor IC features a factory-trimmed reset threshold voltage, which allows it to monitor undervoltage (UV) and overvoltage (OV) conditions. Upon detecting a voltage that is out of the predefined safe operating range, the MAX6398ATT+T asserts a reset signal to prevent system errors. The reset signal remains active until the monitored voltage returns to an acceptable level, plus a reset timeout period to ensure system stability.

The MAX6398ATT+T comes in a small, 6-pin TDFN package, which is ideal for space-constrained applications. Its tiny footprint does not compromise its performance, as it boasts a low quiescent current of just 1.2µA, contributing to extended battery life in portable devices. The device operates over a wide temperature range from -40°C to +125°C, making it suitable for harsh environments and industrial applications.

Key features of the MAX6398ATT+T include:

• Factory-trimmed reset threshold voltage for precise monitoring
• Low quiescent current of 1.2µA for power efficiency
• Manual reset input for system testing and reset control
• Power supply transient immunity for reliable operation
• Wide operating temperature range for versatility in different environments
• Compact 6-pin TDFN package for space-saving designs

This voltage supervisor is an excellent choice for automotive systems, consumer electronics, medical devices, and any other application where power supply integrity is critical. The MAX6398ATT+T's combination of features ensures that it can provide the necessary protection and control for sophisticated electronic systems while maintaining a minimal footprint and power consumption.
