V6340R

The V6340R from Elect-Marin is an ultra-low-cost 3-pin microprocessor reset IC. It continuously monitors the supply voltage (VDD) of an electronic system and generates an appropriate reset signal when the voltage drops below a predefined threshold (VTH). This ensures the reliable functionality of electronic systems by preventing operation outside of safe voltage limits.

The V6340R is available in SOT-23 and TO-92 packages, making it suitable for various board layouts. It features a tight voltage threshold accuracy of ±2.5% and operates over a wide temperature range of -40°C to +125°C. The device boasts low supply current, typically 38 µA at 5V for standard versions and 19 µA for specific switching versions.

Key features include high noise immunity and no requirement for external components. The output can be configured as push-pull or open drain, and it is pin-compatible with industry standards like MAX 809 and MC 33164. Applications span computer electronics, automotive systems, industrial controls, and telecom infrastructure where reliable voltage monitoring is critical.

This IC is designed for applications needing robust voltage detection. Its ability to guarantee reset output state down to VDD = 1V at 25°C further enhances its utility in low-voltage scenarios. The V6340R simplifies system design by integrating essential voltage monitoring functions into a compact package.
