STM1001TWX6F

The STM1001TWX6F is a high performance configurable Power Management IC (PMIC) supervisor that offers a wide array of features in a very small package size. It is designed to replace traditional supervisor designs, such as discrete components and multiple PMIC supervisors, resulting in greater system reliability and improved board design area. The device is designed to assist system power management within a wide range of applications from automotive to consumer applications.

The STM1001TWX6F is built on a configurable, two-level power architecture with a power-on reset circuit and a system reset circuit. The reset circuit is designed to monitor and regulate the system voltage, ensuring a reliable power up sequence. The reset circuit also provides a reset delay and can be programmed to provide an active-low reset on power up, power down and supply sequencing events, giving the system design engineer greater flexibility when designing system reset circuits.

The device also provides over-voltage protection and under-voltage reset protection, protecting the system’s power source against damage due to abnormal voltage conditions. It offers adjustable reset threshold options and active low reset outputs to control MCU reset. The device also features an automatic or manual power-off mode, enabling a wide range of operations for multiple applications such as automotive, consumer and industrial.

The STM1001TWX6F offers robust performance with an operating current of 2µA at 3.3V, and is widely applicable owing to its temperature operating range of -40°C to +125°C. It features an innovative ‘Smart Self Reset’, which ensures the device will automatically reset itself if the conditions change. This ensures that the device is always ready to process the reset from any of the power and voltage monitoring sources.

The STM1001TWX6F also provides adjustable watchdog timers to detect and respond to power faults quickly and reliably. The watchdog timers can be set to expire in intervals of 100ms, 1s and 10s, allowing the device to adjust its response time to different application requirements. The device also includes an adjustable supply input pin, allowing engineers to configure the supply input to work with a wide range of voltages, ideal for applications where the system voltage changes.

In summary, the STM1001TWX6F is a reliable, highly configurable PMIC supervisor designed to help engineers improve board design area and system reliability. It features a wide range of features from power-on reset, over-voltage and under-voltage protection, adjustable watchdog timer and adjustable supply input. The device also features a robust performance and temperature operating range of -40°C to +125°C.
