The LP3470IM5X-4.63 is a precision micro-power voltage supervisor designed and manufactured by Texas Instruments. This component is engineered to provide an essential monitoring function for microprocessor (μP) systems, by asserting a reset signal whenever the V<sub>CC supply voltage falls below a preset threshold of 4.63V. This feature ensures that the μP and its peripherals are reset properly during power-up, power-down, and brown-out conditions.

Packaged in a compact SOT-23-5, the LP3470IM5X-4.63 is ideal for space-constrained applications. It consumes very low power, making it suitable for battery-powered and portable devices where power efficiency is critical. The device's active-low reset output remains asserted for a minimum of 140ms after V<sub>CC has risen above the reset threshold voltage, providing a stable reset signal to the connected microprocessor.

Key Features:

• Voltage Threshold: Precision 4.63V threshold for detecting under-voltage conditions.
• Low Power Consumption: Ideal for battery-operated devices due to minimal power draw.
• Reset Timeout: Ensures a minimum reset pulse width of 140ms.
• Package: Available in a small SOT-23-5 package, suitable for space-limited applications.
• Temperature Range: Operates over a wide temperature range, making it versatile for various environments.

Applications:

The LP3470IM5X-4.63 is a versatile component that can be used in a multitude of applications, including but not limited to:

• Computers and computer peripherals
• Embedded systems
• Battery-powered equipment
• Intelligent instruments
• Portable electronics

With its precise voltage monitoring and reliable reset functionality, the LP3470IM5X-4.63 from Texas Instruments is an excellent choice for safeguarding μP systems against improper operation due to undesirable voltage fluctuations.
