Working Principles

The MAX16134MLG+T is a voltage monitor and reset IC designed to ensure proper operation of electronic systems. It continuously monitors the supply voltage and generates a reset signal when the voltage falls below a predefined threshold. The accurate reset threshold with low voltage hysteresis ensures reliable system reset.

The reset timeout period can be adjusted using an external capacitor connected to the CT pin. This allows flexibility in defining the duration for which the reset signal remains active after the supply voltage rises above the threshold.

In addition to the automatic reset generation, the MR# pin provides a manual reset input. When this pin is pulled low, it immediately triggers a system reset, overriding the automatic monitoring.

The MAX16134MLG+T operates over a wide supply voltage range, making it suitable for various applications. Its low quiescent current ensures power efficiency, while the small package size enables usage in space-constrained designs.

Detailed Application Field Plans

The MAX16134MLG+T finds applications in a wide range of electronic systems that require reliable power management and reset functionality. Some potential application fields include:

1. Embedded Systems: Microcontrollers, DSPs, and FPGAs often require voltage monitoring and reset capabilities to ensure proper operation.
2. Industrial Automation: PLCs (Programmable Logic Controllers) and other industrial control systems benefit from reliable power management and reset functionality.
3. Automotive Electronics: Electronic control units (ECUs), sensors, and other automotive components can utilize the MAX16134MLG+T for voltage monitoring and reset purposes.
4. Consumer Electronics: Smartphones, tablets, and other portable devices can benefit from the small package size and low quiescent current of this IC.
