The STM802RM6F supervisor, an integrated Power Management IC (PMIC) by STMicroelectronics, offer a specialized and quickly reacting solution for all peripheral supply control, power sequencing, and power monitoring needs. This component is suitable for various applications such as residential and commercial cooling, white goods, consumer electronics, portable instruments, power-managed industrial equipment, and computers. Its flexible ball grid array (BGA) package is suitable for consumer products and embedded systems where bigger heat sinks are needed for better thermal management.

The STM802RM6F is based on an 8-bit processor core and features a wide range of interfaces, including I2C, Do Not Disturb (DND), Intelligent Power Lock (IPL), PWM, and serial port. It is equipped with two watchdogs, T1 and T2, to monitor application health, as well as four configurable phase regulators used to sequence power signals for specific designs. This component supports several power supply voltage levels, includes I2C controlled adjustable slew rates and overvoltage protection, and four pulse generators for start-up time sequencing and feedback loops.

The STM802RM6F is compatible with the I2C SMBus protocol, making it easy to integrate into any system. It has a wide range of configurable I2C addresses, allowing it to be used as a master or slave node. It also supports up to eight I2C data exchanges, making it suitable for device monitoring, diagnostics and control. Finally, the STM802RM6F provides an IPL output, allowing the system to quickly respond to changes in load current or temperature.

This supervisor is available in two different models: the STM802RM6F-QS and the STM802RM6F-VBS. Both models use Do Not Disturb (DND) technology to allow the microprocessor to remain in sleep mode without being affected by system noise, resulting in improved performance and power savings. The STM802RM6F-QS features ultra-low quiescent current (IQ) mode, which reduces power consumption when the microprocessor is in idle mode, and the STM802RM6F-VBS is equipped with built-in voltage monitoring, allowing the microprocessor to remain in sleep mode under dynamic power requirements.

The STM802RM6F also provides an advanced solution for power sequencing, which ensures that all of the internal components of the system receive safe levels of current and voltage. The device combines an internal 6-bit DAC, a series of resistive dividers, and dedicated logic circuits to provide precise control of the output voltage in order to protect the system components. The STM802RM6F offers a wide range of configurable power ramp up and ramp down sequences to prevent over-current and over-voltage conditions. The device also supports several over-temperature and under-power conditions to protect the system from external electrical and thermal unbalances.

The STM802RM6F is available in both a BGA package and a QFN package. The BGA package has a 0.8 x 0.65 mm pitch, making it suitable for small robotic, portable, and embedded systems. The QFN package has a 0.4mm pitch and a 1.0 x 1.2mm small footprint, making it suitable for standard and tightly-packed applications. The STM802RM6F offers a combination of small size, low power consumption, and high precision power sequencing capabilities, making it suitable for a wide range of applications.

Overall, the STM802RM6F is an excellent choice for power supply control, power sequencing, and power monitoring in a wide range of applications. Its small size, low power consumption, and precision power sequencing capabilities make it an ideal solution for embedded and portable applications. Its wide range of I2C addresses, DND technology, and pulse generators make it easy to integrate into any system. With a wide range of features, the STM802RM6F is an excellent choice for power management applications.
