• Improves system reliability
• Simple to implement in circuit designs
• Reduces the risk of malfunction due to power supply fluctuations

Additional Details:

The TS809CXBRF monitors the power supply voltage and asserts a reset signal when the voltage falls below a specified threshold. The reset signal remains asserted for a minimum reset pulse width after the voltage rises above the threshold. The reset threshold voltage and reset pulse width are critical parameters for selecting the appropriate reset IC for a specific application. The active-low reset output is compatible with most microprocessor reset inputs. The small package size allows for use in space-constrained applications. The device datasheet will provide specific details on the reset threshold voltage, reset pulse width, and other electrical characteristics. This reset IC provides a reliable and cost-effective solution for ensuring proper system operation in microprocessor-based systems.
