Microchip Technology TCM810MVNB713 - Voltage Supervisor IC

The TCM810MVNB713 from Microchip Technology is a robust voltage supervisor integrated circuit (IC) designed to maintain system integrity by monitoring the power supply voltage levels in digital systems. This small, yet powerful component is an essential part of any system that requires reliable operation through various conditions, including those that may cause power fluctuations.

With its precision voltage monitoring capability, the TCM810MVNB713 ensures that microprocessors, microcontrollers, and other digital systems reset reliably during power-up, power-down, or brown-out conditions. The device has a factory-trimmed threshold voltage set at 4.63V, which is ideal for 5V systems. When the monitored voltage falls below this threshold, the TCM810MVNB713 actively asserts a reset signal, which remains asserted until the voltage returns to a safe operating level and for a specified period after that, ensuring the system has stabilized.

Key features of the TCM810MVNB713 include:

• Low supply current of 9 μA, making it suitable for power-sensitive applications.
• Open-drain RESET output, which allows for flexibility in reset signal interfacing.
• Reset timeout delay of 140 ms (minimum), providing adequate time for system recovery.
• Operating temperature range from -40°C to +85°C, ensuring reliable performance across a wide range of environmental conditions.
• Compact SOT-23-3 packaging, which is ideal for space-constrained applications.

The TCM810MVNB713 is commonly utilized in applications such as portable devices, embedded systems, computers, and any other systems that require precise voltage monitoring for safe operations. Its easy-to-use design requires minimal external components, which simplifies the design and reduces time to market for product developers.

For designers and engineers looking for a reliable solution to protect their digital systems from erratic power supply conditions, the TCM810MVNB713 from Microchip Technology offers a cost-effective and straightforward approach to system voltage supervision.
