Application Field

The MCP1321T-29LE/OTVAO is designed to provide over-voltage, over-temperature and under-voltage protection in automotive, industrial and consumer electronics. It can be used to protect low-cost microcontrollers, such as those found in cars and trucks. The device allows designers to use cost-effective, low-power parts with a fraction of the pins required by traditional power management solutions. The device is also suitable for DIN-rail-mounted systems and offers a wide temperature range for intense industrial applications. In addition, its low power consumption and quick reset speed are attractive features for battery-powered consumer electronics.

Working Principle

The MCP1321T-29LE/OTVAO features a precise comparator and an over-temperature-controlled voltage reset circuit. Over-voltage protection is accomplished by quickly shutting off power when the voltage exceeds its threshold. Over-temperature protection is enabled by the device\'s precision temperature-controlled reset circuit. Under-voltage protection is also provided by quickly shutting off power when the voltage drops below its threshold.

The precise comparator helps the MCP1321T-29LE/OTVAO monitor input voltages and shut off power when necessary. A delay timer is included, allowing the device to accurately reset and re-activate the output when the voltage returns to normal. The device also provides onboard fault timeout and debouncing functions to ensure reliable, accurate operations.

Conclusion

The MCP1321T-29LE/OTVAO is a miniature power management supervisor from Microchip Technology. It is an efficient and cost-effective solution for automated over-voltage, over-temperature and under-voltage protection. The device features a wide input voltage range, ultra-low current consumption, reset delay timer and configurable fault timeout periods. This makes the MCP1321T-29LE/OTVAO an ideal fit for a variety of cost-sensitive, low parts count applications like automotive, industrial and consumer electronics.
