Power management integrated circuits (PMICs) are used in many types of electronic products, from mobile phones to automobiles. PMICs provide essential functions such as power supply sequencing, power rail control, and load balancing. Supervisors are specialized PMICs that provide watch-dog, voltage monitoring, and brown-out detection, among other functions. One example of a supervisor is the S-80837CLNB-B6WT2U.

The S-80837CLNB-B6WT2U is a highly integrated supervisor with three independent monitoring channels and four power-on reset outputs. It is designed for use in embedded systems with processors or microcontrollers requiring reliable power-on and reset control. This chip is ideal for systems that are subject to significant power variations, such as automotive and industrial applications.

The S-80837CLNB-B6WT2U’s main function is to detect power supply problems and reset the system. It consists of three voltage monitoring channels and four power-on reset outputs. The three voltage monitoring channels are programmed to detect over-voltage, under-voltage, or in-range conditions. The four power-on reset (POR) outputs are capable of generating reset pulses to reset the system, when the power-on conditions have been met. Additionally, it includes a watchdog timer, which provides a failsafe mechanism should the system hang.

The S-80837CLNB-B6WT2U can be configured to operate in one of three modes. The first mode is static, where the power-on reset output turns on immediately upon power-up. The second mode is external, where the reset is triggered by an external pulse from an off-chip controller. The third mode is watchdog, which is triggered by a timeout of the internal watchdog timer.

The S-80837CLNB-B6WT2U provides a wide range of integration features, such as an integrated voltage monitor, two separate voltage monitor inputs, and three independent power-on reset outputs. It also features a unique low-power tracking window to reduce power consumption in the lowest power states. The chip is provided in a small BGA package, making it ideal for space-constrained applications.

The S-80837CLNB-B6WT2U is an ideal supervisor for embedded systems where reliable power-on/reset control is required. It provides an integrated voltage monitor, power-on reset outputs, and a watchdog timer. Its low-power tracking window and small BGA package are also excellent features, making it ideal for space-constrained applications.
