Power management integrated circuits (PMICs) provide power regulation and control for various types of electronic systems, ranging from high efficiency digital communications and networks to high power computing and signal processing systems. PMICs provide a broad range of functions including voltage monitoring, voltage regulation, automatic fault diagnosis and protection, power sequencing, and power module management. Supervisors are a type of PMIC which integrate advanced, multiple-level monitoring for system reliability in a wide variety of commercial, industrial, and mobile applications.
The MAX6423XS46+T is a microprocessor Supervisor with programmable supervisor circuitry, voltage monitoring and system reset generation in a 6-pin small outline SOT-23 package. Additionally, this IC supports a variety of features, which make it suitable for use in a wide range of power management applications. This article looks at the MAX6423XS46+T application field and its working principle in detail.
Application Field
The MAX6423XS46+T is a multi-function supervisor IC suitable for a wide range of applications. These include backup battery monitoring, system temperature protection and detection, reset generation and protection control, and over voltage protection, among others. It is also well-suited for use in high-efficiency digital communications and networks, high power computing and signal processing systems, and other applications which require power management and monitoring. The tiny 6-pin package makes this IC suitable for use in space-constrained environments, including portable and handheld devices.
Working Principle
The MAX6423XS46+T supervises an external power supply and supplies an active-low reset signal when the voltage is out of range. It has an adjustable trip point with a reset interval of 100ms. The MAX6423XS46+T also employs an internal temperature-controlled switch to enable output overtemperature protection. Additionally, the IC monitors the power supply voltage, input voltage range, and output voltage range. If the voltage is out of range, the IC provides a reset signal. The trip point is externally adjustable, allowing users to customize the operation according to the application requirements.
The MAX6423XS46+T also features an internal watchdog timer which generates a reset signal if the timer expires. The watchdog timer is triggered by a rising or falling edge of the active-low WP pin. The timer’s duration is adjustable with an external capacitor. It provides two voltage monitor input pins (V1 and V2) which monitor two different supply voltages and can be adjusted independently. The IC also provides two active-low reset output pins (R1 and R2) for separate external circuitry.
Overall, the MAX6423XS46+T is a compact, low-power Supervisor IC with a wide range of features and a small 6-pin package. It is suitable for a variety of applications including high efficiency digital communications and networks, high power computing and signal processing systems, and other applications requiring power management and monitoring. It is easy to use, with an adjustable trip point and a watchdog timer, as well as two voltage monitor input pins and two reset output pins.
