Package

The LP3470IM5X-3.08 is a voltage supervisor IC featuring a SOT-23-5 package. This small-outline package is commonly used for its compact size, ideal for space-constrained applications such as portable and battery-powered devices.

Pinout

The LP3470IM5X-3.08 is a voltage supervisor IC designed by Texas Instruments. It monitors the power supply voltage in microcontroller systems and initiates a reset when the voltage falls below a specified threshold.
Pin Count:
The LP3470IM5X-3.08 comes in a SOT-23 package with 5 pins.
Functions:
1. VDD (Pin 1): This is the power supply input pin. It monitors the system supply voltage.
2. GND (Pin 2): Ground reference for the device.
3. MR (Manual Reset) (Pin 3): This is an input pin for manual reset. When driven low, it forces a reset condition.
4. RESET (Pin 4): This is the output pin that signals a reset condition to the connected microcontroller or system logic. It is an active-low output, indicating that the supply voltage is below the threshold or the manual reset is active.
5. NC (Pin 5): No connection, typically not used in circuit designs for functional purposes.
This IC is typically used to ensure reliable system operation by supervising supply voltage levels and preventing the system from operating under incorrect power conditions.
