The LP3470M5-4.63 from Texas Instruments is a sophisticated microprocessor supervisory circuit designed to monitor system voltages and provide an accurate reset signal for microprocessors, microcontrollers, and other digital systems.

• Package: Comes in a compact SOT-23 package, suitable for high-density circuit board applications.
• Function: Monitors the system voltage and resets the system when the voltage drops below a preset threshold.
• Threshold Voltage: Precision voltage reference and comparator monitor the system voltage with a threshold voltage accuracy of ±1.5% over the entire temperature range.
• Reset Output: Active-low reset output, asserted when input voltage decreases below the reset threshold voltage. Remains asserted for a minimum of 140ms after the input voltage rises above the reset threshold voltage.
• Manual Reset Input: Allows the user to manually initiate a reset, providing an additional level of control and flexibility.
• Supply Current: Low supply current of 15µA, making it energy-efficient.
• Temperature Range: Operates over a wide temperature range of -40°C to 85°C.
• Compliance: RoHS compliant and lead-free (NOPB), environmentally friendly.

In conclusion, the LP3470M5-4.63 from Texas Instruments is a high-performance, feature-rich microprocessor supervisory circuit that offers a compact, energy-efficient, and reliable solution for monitoring system voltages and providing a reset signal in a wide range of digital systems.
