The MAX982CSA from Maxim Integrated is a high-precision voltage detector designed for portable and battery-powered applications that demand minimal power consumption. This device is a part of a family of micro-power voltage detectors that offer a variety of reset thresholds and output options.
This component features a low supply current of only 1.5µA, which is particularly advantageous for prolonging battery life in portable devices. It operates over a wide voltage range from 1.2V to 5.5V, making it versatile for various applications. The MAX982CSA comes in a compact SC70 or SOT23 package, suitable for space-constrained designs.
The device provides a critical monitoring function by asserting a reset signal whenever the monitored voltage falls below its preset threshold. The reset output remains asserted for a minimum of 140ms after the voltage rises above the reset threshold, ensuring proper system reset. This feature is essential for microcontrollers and other digital systems that require a stable power-on reset or a brownout protection.
The MAX982CSA offers a choice of reset voltage thresholds, which are factory-trimmed for high accuracy without the need for external components. This precision enables the device to provide reliable monitoring for specific voltage requirements. Moreover, it comes with two output type options: push-pull active-low RESET or open-drain active-low RESET-bar. Designers can select the appropriate configuration based on the requirements of their specific application.
Maxim Integrated's commitment to quality ensures that the MAX982CSA meets stringent performance standards. Applications that can benefit from this voltage detector include portable/battery-powered equipment, computers, controllers, intelligent instruments, critical μP and μC power monitoring, and automotive systems.
In conclusion, the MAX982CSA is a smart choice for any designer looking for a reliable, high-performance voltage detector that conserves power and space without sacrificing functionality.
