ON Semiconductor CAT823ZSDI-GT3 Voltage Supervisor

The CAT823ZSDI-GT3 is a high-performance voltage supervisor device designed by ON Semiconductor, a leading provider of semiconductor-based solutions. This precision voltage monitoring IC is engineered to ensure that electronic systems operate optimally by monitoring the power supply voltage and providing a reset signal to the host processor when necessary.

Featuring a low power consumption and a compact SOT-23 package, the CAT823ZSDI-GT3 is ideal for portable and space-constrained applications. The device boasts a factory-trimmed threshold voltage, which allows for accurate monitoring of the system voltage without the need for external components. This makes it a convenient and cost-effective solution for system designers.

The voltage supervisor includes an active-low reset output, which is asserted when the monitored voltage drops below the specified threshold. The reset signal remains active until the voltage recovers and a built-in delay time has elapsed, ensuring the system has stabilized before resuming operation. This delay time is also factory-programmed, providing a reliable reset timing without additional timing components.

Key features of the CAT823ZSDI-GT3 include:

• Factory-programmed V<sub>TH options for different voltage thresholds
• Low supply current, suitable for battery-operated devices
• Guaranteed reset valid to V<sub>CC = 1.0V
• Immunity to short V<sub>CC transients
• Active-low reset output
• Operating temperature range from -40°C to +85°C

With its robust design, the CAT823ZSDI-GT3 is highly immune to short power supply transients, ensuring reliable operation even in noisy environments. This makes it an excellent choice for a wide range of applications, including microcontrollers, computers, controllers, intelligent instruments, and portable electronics that require precise voltage monitoring and secure system reset functionality.

In summary, the CAT823ZSDI-GT3 from ON Semiconductor is an essential component for maintaining system integrity through precise power monitoring and control. Its ease of integration, low power consumption, and high accuracy make it a valuable addition to any power-sensitive electronic system.
