Power management integrated circuits (PMICs) are a critical component of embedded system and portable device design. PMICs manage the various power rails that provide the energy required for a system to operate, ranging from batteries to renewable energy sources. The STM707M6F is a low-voltage, voltage supervisor designed to monitor input voltages and generate system-reset signals. It is a member of STMicroelectronics’ STM707M family of advanced, low-voltage, voltage supervisors that offers a range of features and low-power management capabilities.

The STM707M6F is designed to monitor the battery and supply voltages in handheld and embedded applications. It features low power, low current, and low operating temperature, which boosts the system\'s battery life and reduces operating temperature while maintaining the same operating voltage. It also features a reset pulse width selectable from 0.3 ms to 3.3 ms and a reset pulse interval selectable from 0 ms to 1.44 s. The STM707M6F also includes a multi-input debounce for improved reset timing accuracy, an on-chip undervoltage detector, and an output stop function.

Application Field

The STM707M6F is suitable for use in numerous applications in the consumer, automotive, industrial, and medical fields. It is designed to monitor the battery and supply voltages of small, low-voltage systems in battery-operated and portable products, such as TV remote controls, cordless phones, digital still cameras, two-way radios, PDAs, and other embedded systems.

It can also be used in automotive onboard systems, including fuel-level monitoring, engine control, and powertrain control, as well as medical applications, such as patient monitors, medical instrumentation, and laboratory equipment.

Working Principle

The STM707M6F monitors battery and power supply voltages and generates system-reset signals. It uses an on-chip, low-voltage undervoltage detector (LVD) to compare the supply voltage to the threshold voltage. When the supply voltage drops below the threshold, the device generates a low-voltage reset signal.

The STM707M6F also uses a multi-input debounce as a part of its reset signal generation circuitry. This feature ensures improved accuracy of the reported reset times and ensures that reset signal initiation times are maintained over a wide range of input voltage supply signals.

The STM707M6F includes a reset pulse width selectable from 0.3 ms to 3.3 ms, and a reset pulse interval selectable from 0 ms to 1.44 s. This feature allows the user to customize the reset parameters according to the system needs. The reset signal is output through an open-drain output, allowing direct connection of the device to external CMOS logic circuits.

The STM707M6F also includes an output stop function which can be used to disable the output when the reset signal is not required. This feature allows the device to consume even less power when the reset signal is not required.

The STM707M6F is available in a small 5-pin SOT23 package, making it ideal for operation in space-constrained applications. It is also designed to operate over a wide range of temperatures, from -40°C to +125°C, enabling a wide range of low-power applications.

Conclusion

The STM707M6F is an advanced, low-voltage voltage supervisor from STMicroelectronics designed to monitor input voltages and generate system-reset signals. It features low power, low current, and low operating temperature, multi-input debounce circuitry, an on-chip undervoltage detector, and an output stop function. It is suitable for use in numerous applications in the consumer, automotive, industrial, and medical fields, and is available in a small 5-pin SOT23 package.
