PMIC, or power management integrated circuit, is a kind of integrated circuit, which is used to monitor, control and manage different areas in the power system of electronic devices. There are various types of PMIC according to the applications and principles, such as supervisors, regulators, converters and other stand-alone power management integrated circuits. STM6510SCACDG6F, as a supervisors type PMIC, it has different application fields and working principles.

Application Fields

STM6510SCACDG6F is a single-channel supervisor, suitable for use in system reset circuit in automotive computing and communication applications. It can be widely used in the vehicle-fault diagnosis, driving information collection and monitoring, such as RPM, brake pad, gear box, power management, drive axle and more. It is also can be used in the non-automotive applications, like home appliences, industial controls and telecommunication systems.

The core of STM6510SCACDG6F is a monolithic CMOS integrated circuit that can detect an extended range of voltages with respect to the local ground, within the extremes of the 3V~30V. It features an integrated power-on-reset (POR) function, which helps to apply a reset signal to the system under abnormal conditions. The reset output feature can be controlled by either a reset input or a watchdog input.

Working Principle

When the power supply voltage is greater than the POR threshold (2.1V), the interal POR circuit will turn on the reset output. The reset output RST is then connected to the reset pins of the system microcontroller (MCU). During the voltage supply is normal, RST will be low. When there is a deviation from the normal voltage, the POR circuit will detect the voltage change and reset the MCU, therefore the system can be reset and then continue the normal operation.

The STM6510SCACDG6F also provide a configurable watchdog input called WDON, it can realize the WDO reset function. In normal operations, the WDON will be reset to 0 periodically. When system malfunction, and the WDON is not reset timely, the pre-setting time of expiration is reached, then the supervisor will generate a reset signal and reset the system, therefore the system can be restart and back to normal.

The STM6510SCACDG6F can be used as a basic stand-alone supervisor to protect the system from unexpected errors. It is designed for the autonomous powering of various analog and digital systems. This supervisor can also be applied in many situation which requires higher endurance in harsh environment, like high-temperature and avalanche immunity.

In a nutshell, STM6510SCACDG6F, as a supervisors type PMIC, it has extensive applications in automotive industry and other industry. The supervisor can provide an extended voltage range of 3V~30V with respect to the local ground, it also equipped with a power-on-reset and configurable watchdog input. This supervisors PMIC is surely your best choice to keep your system working well.
