What are the key features of STM795TM6E?
- Integrated watchdog timer monitors software execution and asserts active-low reset output if the watchdog is not serviced within the programmed timeout period
- Battery backup switch controller enables seamless switchover from main supply to backup battery, protecting volatile SRAM and RTC data during power interruptions
- Wide 1 V to 5.5 V operating range supports both 3.3 V and 5 V system designs in a single-channel supervisor using only 8 pins
What is STM795TM6E used for?
The STM795TM6E is used in embedded systems and industrial controllers where reliable power sequencing and watchdog supervision are essential for system integrity. It protects SRAM-based data loggers and real-time clocks by switching to a backup battery when the main supply drops, ensuring data retention during brief outages. The watchdog function is commonly used in autonomous remote monitoring equipment to recover from software hangs without human intervention, reducing field-service costs.

Frequently Asked Questions
How does the STM795TM6E watchdog function protect an embedded system from software lockups in unattended field deployments?
The STM795TM6E watchdog timer asserts an active-low reset pulse on its RESET output if the host microcontroller does not service the watchdog within the programmed timeout window, forcing a clean system restart without human intervention. In unattended field equipment such as remote data loggers or industrial automation controllers, this hardware watchdog provides a last-resort recovery mechanism that restores normal operation within milliseconds, minimizing data loss and avoiding costly field-service calls.
Over what supply voltage range does the STM795TM6E operate, and does it support both 3.3 V and 5 V system designs?
The STM795TM6E operates across 1 V to 5.5 V, directly covering 3.3 V microcontroller systems and 5 V legacy logic without any external level-shifting. The battery backup switch function activates when the primary supply falls below the device threshold, switching a connected backup cell to sustain 1 channel of powered circuitry such as an RTC or SRAM, ensuring data retention during brownouts lasting from milliseconds to hours.
For a compact industrial controller PCB, how many external components does the STM795TM6E require to implement watchdog supervision and battery switchover?
The STM795TM6E integrates the watchdog timer, battery switchover comparator, and active-low reset driver into a single 8-pin SOIC package, requiring only 1 or 2 bypass capacitors and the backup battery connection as external components. This highly integrated approach saves board space compared to implementing a discrete watchdog plus separate power-fail comparator and battery-switch MOSFET, which typically needs 5 or more components and at least 50 mm² of PCB area.
