Maxim Integrated MAX6382XR26D1+T Microprocessor Reset Circuit

The MAX6382XR26D1+T from Maxim Integrated is a high-quality microprocessor (μP) supervisory circuit designed to monitor power supplies in μP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems that require a reset. This component is ideal for portable, battery-operated applications due to its low power consumption and small footprint.

With a factory preset V_CC reset threshold voltage of 2.63V, this reset circuit ensures that the μP resets cleanly during power-up, power-down, and brown-out conditions. Upon detecting a voltage below the threshold, the MAX6382XR26D1+T asserts a reset signal to prevent system errors. The reset signal remains asserted for a minimum of 140ms after V_CC has risen above the reset threshold, providing ample time for the system to stabilize.

The device comes in a compact, 3-pin SC70 package, which is highly space-efficient and suitable for high-density circuit boards. Its small size makes it an excellent choice for space-constrained applications such as handheld devices.

Key features of the MAX6382XR26D1+T include:

• Precise V_CC Monitoring – Ensures accurate monitoring of the system voltage.
• Low Power Consumption – Ideal for battery-powered applications where power efficiency is critical.
• Power-Supply Transient Immunity – Protects against glitches and transients on the power supply line, ensuring stable operation.
• No External Components Required – Simplifies design and reduces overall system cost.
• Guaranteed Reset Valid to V_CC = 1V – Ensures reliable reset operation even at low voltages.

The MAX6382XR26D1+T is designed for a wide range of applications, including computers, controllers, intelligent instruments, portable/battery-powered equipment, and critical μP power monitoring. With its robust design and reliable performance, this reset circuit from Maxim Integrated provides a simple and cost-effective solution for system stability and protection.

Maxim Integrated's commitment to quality ensures that the MAX6382XR26D1+T meets the stringent requirements of modern electronic systems, offering designers a dependable and straightforward solution for μP supervision.
