ON Semiconductor CAT811MTBI-T3 Voltage Supervisor IC

The CAT811MTBI-T3 from ON Semiconductor is a high-performance voltage supervisor integrated circuit (IC) designed to provide precision monitoring of power supplies in digital systems. This compact and reliable component is an essential part of any system where consistent and accurate voltage supervision is critical to ensure proper operation and protection of sensitive electronic circuits.

With its small SOT-23 package, the CAT811MTBI-T3 is ideal for space-constrained applications, offering a minimal footprint without compromising on functionality. The device is capable of monitoring a nominal threshold voltage of 4.38V, making it suitable for a wide range of applications, including microprocessor and microcontroller-based systems, portable and battery-powered equipment, and other electronic devices that require voltage supervision.

The CAT811MTBI-T3 features a precision voltage reference and comparator circuit that monitors the VCC for under-voltage conditions. When the VCC falls below the threshold voltage, the reset output is asserted, which remains active until the VCC rises above the threshold voltage plus a hysteresis amount, ensuring a clean reset signal is provided without false triggering due to supply noise or transients.

The device also offers a 140 ms (minimum) reset pulse width, which guarantees sufficient time for the system to stabilize after a reset condition. This feature is particularly useful in complex digital systems where a longer reset pulse is necessary to ensure a proper restart of the system.

Furthermore, the CAT811MTBI-T3 consumes low power, making it an excellent choice for power-sensitive applications. It also supports a wide operating temperature range from -40°C to +85°C, ensuring reliable performance across various environmental conditions.

In summary, the CAT811MTBI-T3 voltage supervisor from ON Semiconductor is a robust and precise solution for systems requiring accurate monitoring and control of their power supply voltages. Its compact size, low power consumption, and wide operating temperature range make it an excellent choice for designers looking to enhance the reliability and safety of their electronic products.
