Introduction

DS1832 is one of the most popular and versatile PMIC (Power Management Integrated Circuit) – supervisors from Maxim Integrated. Maxim Integrated is known for their innovative solutions for managing current and voltage in high reliability applications, and their PMIC - Supervisors are designed for reliability and power saving operations. The DS1832 series of supervisors are designed to provide the necessary current, voltage and safety features for circuits and equipment needing excellent performance, reliability and cost savings.

Features

The DS1832 supervisor from Maxim Integrated is designed to provide a range of features and functionality to ensure the most reliable performance for a circuit or system. It offers a wide range of features such as an adjustable overvoltage and undervoltage protection, adjustable current and voltage monitoring, reset and manual reset, latched outputs and an open- or short-circuit detection. It can also provide power-on reset and power-good latch LED indications, digital monitoring of volts and currents, adjustable fault output and power-fail comparator thresholds. The DS1832 can be used in systems operating between 2.5V to 15V and is capable of driving loads up to 1A.

Application Field

The DS1832 PMIC - Supervisors from Maxim Integrated is designed to provide power management solutions for a variety of applications. It is ideal for applications such as consumer electronics, automotive and industrial systems, medical equipment, computer and communication systems and energy management. The DS1832 series is designed to operate over a wide battery voltage range making it suitable for a wide range of applications. It can be used as a power source supervisor for systems with batteries or used to provide shut down and restart of systems with a wide input voltage range.

Working Principle

The DS1832 PMIC - Supervisors from Maxim Integrated offer an operating voltage range from 2.5V to 15V which allows them to be used in a wide range of systems with different input voltages. It provides adjustable overvoltage and undervoltage protection, adjustable current and voltage monitoring, reset and manual reset and latched outputs. The DS1832 also includes a power-on reset and a power-good latch LED indication to provide real-time monitoring of system operation and state.In operation, the DS1832 has two inputs, VCCand EN. VCC is the operating voltage input, while EN is the enable input. The device has two outputs, RESET and POWER-GOOD. When the device is enabled, VCC has to be greater than the voltage threshold for the device to be active. Once active, the device continuously monitors the system for any fault conditions. If a fault condition is detected, the RESET output is asserted low and the device works to reset the system’s operation to a safe state.The POWER-GOOD output of the DS1832 is typically connected to a power-on reset or watchdog timer to indicate when the power supply is stable, or if there is a brownout or overvoltage condition. This helps ensure that the system is always operating within its safe limits.

Conclusion

The DS1832 PMIC - Supervisors from Maxim Integrated is an excellent choice for reliable power management solutions in high reliability applications. It offers a wide range of features including adjustable overvoltage and undervoltage protection, adjustable current and voltage monitoring, reset and manual reset, latched outputs, open- or short-circuit detection and power-on reset and Power-Good latch LED indication. With its wide voltage range and ability to drive loads up to 1A, it is an ideal solution for battery powered systems, automotive and industrial systems, medical equipment, computer and communication systems, and energy management systems.
