MAXIM INTEGRATED / ANALOG DEVICES MAX6337US20D3T Microprocessor Reset Circuit
The MAX6337US20D3+T is an ultra-low voltage, low-power microprocessor reset circuit housed in a 4-pin SOT-143 package. It monitors power supplies ranging from 1.8V to 3.3V and ensures system reliability by eliminating the need for external components and adjustments. The device features a debounced manual reset input and asserts a reset signal whenever the supply voltage drops below a preset threshold or when manual reset is activated. Reset remains active for a specific timeout period after voltage recovery or manual reset deassertion. It is designed to ignore fast transients on the supply voltage, making it suitable for critical microprocessor and microcontroller power monitoring, controller systems, and intelligent instruments. The circuit supports a supply voltage range from 1V to 5.5V, operates over temperatures from -40°C to 125°C, and has an active-low, open-drain reset output with a threshold voltage of 2V. It consumes low current—approximately 3.3µA at 2.5V and 3µA at 1.8V—and is fully specified over temperature with transient immunity. The device is cost-effective, requiring no external components, and is pin-compatible with MAX811, MAX812, MAX6314, and MAX6315. Typical applications include system monitoring, consumer electronics, portable devices, and automotive systems.
