PMIC - Supervisors

Today, in many high-tech applications, power management integrated circuits (PMICs) are essential components, such as the S-1000C45-M5T1G. This supervisor device is capable of monitoring power supplies and providing output signals for sequence and fault protection applications. It is designed for automotive and industrial applications, and provides reliable, user-friendly design solutions.

Overview of S-1000C45-M5T1G

The S-1000C45-M5T1G is a high-speed micropower supervisor device manufactured by ON Semiconductor. It is a 3.3V device that offers a watchdog timer, reset outputs, and a watch-dog enable output. It also provides an adjustable reset and watchdog timer threshold, which are enabled/disabled by an open drain enable/disable pin. The supervisor device has the capability of completing a sequence within two minutes.

Application Field of S-1000C45-M5T1G

The S-1000C45-M5T1G is mainly utilized in monitoring battery voltage, supplying power-cycle intervals, system noise suppression, and other functions related to overseeing the power management of a system. It can be used in a variety of applications, including automotive and industrial, as a reset and watchdog supervisor to provide basic fault protection of microcontrollers and system peripherals. The S-1000C45-M5T1G can also be used in applications where a signalled reset or watchdog alert is required. These applications may include embedded systems for data logging, medical and handheld instrumentation, medical devices, wireless systems, or automotive systems. The device is designed with precision timing and provides reset sequence for fast initialization of multiple ICs and other components.

Working Principle of S-1000C45-M5T1G

The S-1000C45-M5T1G supervisor device has several functional blocks, including a voltage monitor, an oscillator, a reset timer, a watchdog timer, and a watchdog enable output. When power is applied to the device, the voltage monitor checks the voltage on the supply line to determine if it meets the reset threshold voltage. If the reset threshold voltage is not met, the device will not operate and will ignore all inputs until the reset threshold is reached. When the reset threshold voltage is reached, the reset pin is asserted to apply reset to the device and a reset pulse is sent. This reset pulse is used to initialize the device and inform it that all of the parameters are in their default states. After the reset pulse is sent, the voltage monitor will watch for a change in the voltage level. If the voltage drops below the reset threshold, the monitor will again reset the device and the reset pulse is sent again. The oscillator is used to generate a clock signal for the reset timer and watch-dog timers. The reset timer is used to determine when a reset pulse should be sent. Once the reset process is complete, the watchdog timer is used to monitor the activity of the system and detect system faults or errors. If it does not detect any changes in the system, the timer will expire and send a watch-dog enable output. This output is used to reset the device, the processor, or other components.

Conclusion

The S-1000C45-M5T1G is an essential component in modern high-tech applications, providing reliable solutions for reset and watchdog monitoring. With its precision timing and design, the device can be used in a variety of applications, including automotive and industrial. Its ability to monitor power supplies and provide output signals for sequence and fault protection makes it an excellent choice for various applications.
