The MAX6466XR20+T is an advanced system supervisor and power control IC integrated into a small single-lead package. The MAX6466XR20+T is mainly used for power-on reset and system supervision, including precision reset timing and circuit reset threshold detection for systems for consumer, automotive and industrial applications. The MAX6466XR20+T combines both a voltage monitor, with a supply voltage range from 1.2V to 7.0V, and also digital logic that offers either a power-on reset with adjustable reset delay and accuracy or a manual reset type using an external push-button.

Application Field

The MAX6466XR20+T is ideal for applications that require precision supply and reset monitoring. This is especially critical for system stability and reliability in mission critical applications, where the MAX6466XR20+T ensures that the system has adequate power at all times. It is also suitable for a wide range of applications, including embedded microcontroller-based systems, PC motherboards, FPGAs, ASICs, microprocessors, and more.

Working Principle

The MAX6466XR20+T uses a voltage monitor as the core part of its circuit. The voltage monitor is designed to monitor the system power supply voltages and detect any anomalies. When the input voltage falls below a preset threshold, the MAX6466XR20+T will output an active-low reset pulse. This reset pulse can be used to reset the system or to trigger any required reset condition. When the input voltage rises above the preset threshold, the reset pulse is removed.

The MAX6466XR20+T also offers two additional outputs for user control, as well as two reset outputs. The first output is a logic-level output that is used to trigger a reset when the input voltage falls below a user-determined threshold. The second output is an active-high reset output. This output is used to directly reset the system, either manually or via an external push-button switch.

The MAX6466XR20+T is designed to ensure that the system operates correctly during start-up and remains stable during operation. The device\'s various outputs can be tailored to meet any specific application requirements. The MAX6466XR20+T also offers excellent reset accuracy with a precision of <+/- 0.5% from 0 V to maximum voltage over temperature. This makes it ideal for mission-critical applications such as aerospace and military.
