PMIC - Supervisors: DS1833Z-15 Application Field and Working Principle

PMIC stands for Power Management Integrated Circuit. It is a form of integrated circuit (IC) which is specifically designed to handle power management and deliver power output to a broad range of devices and circuits. Supervisors, or voltage supervisors, are special purpose ICs that are used to monitor the applied power supply voltages and protect the device from unintended overvoltage situations. In this respect, a supervisor is a type of PMIC that can be used to manage voltage regulation and power delivery to ensure safe and stable operation of electronic devices and circuits. The DS1833Z-15 is a high performance CMOS-based supervisor device from Maxim Integrated. It is a highly efficient voltage supervisor that has been designed to increase the accuracy, flexibility and robustness of power management designs. The supervisor is featured with a wide range of features for easy implementation in systems that require precise low-voltage measurements, improved load transient response and high temperature accuracy. The DS1833Z-15 supervisor is designed to monitor one or two supply voltages and provide output power regulation and protection against accidental overvoltages or short circuits. The supervisor is available in a 5-pin SOT-23 package and requires minimal external components. It has an operating temperature range of -40°C to +85°C and supports common output voltage levels of 1.5V, 1.8V, 2.5V and 3.3V. The DS1833Z-15 has a wide input dynamic range of 0.8V to 8.0V and includes precision voltage comparators with a ±1% overvoltage threshold accuracy. It also features a variable reset timeout function, a dual reset output and a reset open-drain output for system reset. The device also offers a supply voltage monitor which keeps the output voltage on track when the supply voltage changes. Other features of the device include a robust shutdown on a temporary brownout condition, reverse battery protection and a programmable reset timeout period. The DS1833Z-15 also includes a wide range of safety and protection features such as circuit protection against input voltage transients, input overvoltage protection, short circuit protection and current limiting when an output is shorted. Furthermore, the device has a thermal shutdown feature to protect the system from overheating. In conclusion, the DS1833Z-15 is an excellent supervisor IC designed to handle complex power management and deliver reliable output to the system. With a wide range of features and protection, the device ensures maximum system performance and stability for the most demanding applications.
