MAX6333UR18D3-T Description

Short technical summary and product information.

The MAX6333UR18D3-T from Analog Devices is a microprocessor supervisory circuit that monitors power supply voltages in 1.8V to 3.3V systems. It asserts a reset signal when the VCC supply voltage drops below a preset threshold, maintaining the reset for a specified timeout period after the voltage recovers. This device is designed to increase system reliability and reduce component count.

 

Key electrical specifications include a minimum reset threshold of 1.6V, an active-low push-pull reset output, and a minimum reset timeout of 100ms. It operates with a low supply current of 3.3μA and is guaranteed to be in the correct state for VCC down to 0.7V. The reset comparator is designed to ignore fast transients on VCC.

 

This supervisory circuit is available in a compact 3-pin SOT-23 package, making it suitable for space-critical applications. It is ideal for critical μP/μC power monitoring in portable, battery-powered equipment, controllers, and intelligent instruments. The MAX6333UR18D3-T is pin-compatible with other Maxim supervisory circuits like the MAX809/MAX810 and MAX6326/MAX6327/MAX6328.
