Product Description
Microchip MIC803-29D2VM3-TR is a single voltage supervisor integrated circuit designed for precise power supply monitoring in microprocessor-based systems. The device includes one voltage supervisor with an open drain RESET output packaged in a compact 3-pin SOT-23 form factor. It features a reset threshold voltage of 2.93 V and operates reliably within a temperature range from -40°C to 125°C, making it suitable for industrial and commercial electronics applications.
This voltage supervisor provides an accurate power-on reset function by asserting a reset signal when the supply voltage drops below the threshold. The reset is maintained for a selectable timeout period (20 ms, 140 ms, or 1120 ms) after the power supply voltage has recovered, ensuring stable system startup and reducing the risk of erratic operation.
The device monitors voltages from a minimum of 1 V up to a maximum supply of 5.5 V, ensuring compatibility with various low-voltage microcontrollers and electronic devices. With a typical supply current consumption of only 4.5 μA at 3.6 V, the MIC803 supervisor is optimized for low power consumption scenarios.
The SOT-23 package measures just 2.3 mm in length and 2.9 mm in width, lending itself to space-constrained layouts on printed circuit boards. The device is RoHS compliant, adhering to environmental and safety standards.
Applications for the MIC803-29D2VM3-TR voltage supervisor include industrial equipment control, embedded systems, consumer electronics, and automotive electronics (where automotive-specific standards are not mandatory).
Operates with a low power supply current of 4.5 μA typical at 3.6 V. Provides a stable reset signal with selectable reset timeout options. Compact 3-pin SOT-23 form factor for efficient PCB integration. Wide operating temperature range from -40°C to 125°C for robustness.
Accurate reset voltage threshold with 2.5% tolerance over temperature.
Choose the Microchip MIC803-29D2VM3-TR for reliable and precise voltage supervision in power-sensitive embedded applications. Explore more Voltage Supervisor components in the Electronics & Electricals category at EnvMart.
