Maxim Integrated MAX6753KA26+ Low-Power Voltage Detectors

The MAX6753KA26+ is a high-quality voltage detector designed by Maxim Integrated, renowned for its precision and low-power consumption. This device is engineered to monitor supply voltages and provide a reliable reset signal to microprocessors (µPs), microcontrollers (MCUs), and other digital systems, ensuring proper operation during power-up, power-down, or brown-out conditions.

Operating from a 2.5V to 5.5V supply voltage range, the MAX6753KA26+ is versatile and can be integrated into a wide array of applications. It features a factory-trimmed reset threshold voltage set at 2.63V, which is ideal for managing 2.7V and 3.3V powered systems. The device offers a ±2.5% reset threshold accuracy over the entire temperature range of -40°C to +125°C, providing reliable performance even in extreme conditions.

This voltage detector has an open-drain reset output configuration, which remains asserted for a minimum of 140ms after V_CC has risen above the reset threshold. This ensures a proper system reset and allows enough time for the power supply and processor to stabilize. The MAX6753KA26+ consumes an ultra-low supply current of only 3.5µA, making it an excellent choice for battery-powered and portable devices where power efficiency is crucial.

Maxim Integrated has packaged the MAX6753KA26+ in a small 8-pin SOT-23 package, which is both space-saving and suitable for automated assembly processes, facilitating its integration into compact designs. The device also includes an active-low manual reset input, which provides a convenient way to initiate a system reset manually.

Whether it's for consumer electronics, portable devices, or industrial systems, the MAX6753KA26+ offers a robust and reliable solution for voltage monitoring and system reset functions. Its precision, low power consumption, and small footprint make it an excellent choice for designers looking to enhance system reliability and extend battery life.
