The MAX814KESA+ is a compact and efficient voltage supervisor integrated circuit (IC) designed by Maxim Integrated, a renowned manufacturer of analog and mixed-signal engineering solutions. This small, yet powerful IC ensures reliable operation of microprocessors (μPs), microcontrollers (MCUs), and other voltage-sensitive devices by monitoring their power supplies.
The MAX814KESA+ is housed in a space-saving 8-pin SO package, which is suitable for surface-mount technology (SMT) and offers a streamlined solution for printed circuit board (PCB) design. The device features a precise factory-set voltage threshold, which triggers a reset signal when the monitored voltage falls below this critical level. This reset signal is maintained for a minimum of 140ms after the voltage returns to an acceptable level, ensuring that the system has adequate time to stabilize before resuming operation.
With its wide operating voltage range, the MAX814KESA+ can accommodate various applications, supporting supply voltages from 1.2V up to 5.5V. This versatility makes it an ideal choice for portable devices, consumer electronics, and any system requiring a dependable power-on reset or voltage supervision function.
Additional features of the MAX814KESA+ include a debounced manual reset input, allowing for an external override of the reset signal, which can be useful for testing or manual system resets. The device also offers a low quiescent current, which is essential for battery-powered applications where power conservation is critical.
The MAX814KESA+ is characterized by its robustness and reliability, with built-in immunity to short voltage transients, which enhances system stability and prevents false triggering. Its temperature range of -40°C to +85°C ensures operation in a variety of environmental conditions, making it a reliable choice for industrial and automotive applications as well.
In summary, the MAX814KESA+ from Maxim Integrated is a highly reliable voltage supervisor IC that provides essential protection to sensitive electronic systems, ensuring that they operate within their specified voltage ranges and recover gracefully from power disturbances.
