Frequently Asked Questions
What is the reset threshold voltage of LM809M3-4.63/NOPB?
The LM809M3-4.63/NOPB has a factory-set reset threshold voltage of 4.63V with ±2% accuracy. When VCC drops below 4.63V, the active-low open-drain RESET pin is asserted within the specified timeout period, protecting the system from brown-out conditions.
What package does the LM809M3-4.63/NOPB come in?
The LM809M3-4.63/NOPB is available in a 3-pin SOT-23 (SC-70 footprint compatible) package. This ultra-compact package is ideal for space-constrained PCB layouts in portable and handheld devices. The 'M3' suffix denotes the SOT-23 package, and 'NOPB' indicates lead-free, RoHS-compliant construction.
What are the typical applications for the LM809M3-4.63/NOPB?
This voltage supervisor is commonly used in microcontroller reset circuits, DSP power-on-reset, battery-powered portable equipment, industrial control systems, and telecom power management. It monitors the supply rail and holds the MCU in reset until VCC is stable above the 4.63V threshold.
What are compatible alternatives to the LM809M3-4.63/NOPB?
Compatible alternatives include the MAX809S (Maxim, 4.63V threshold, SOT-23), MCP100T-475I/TT (Microchip, 4.75V, SOT-23), and the TLV803S (TI, similar supervisor family). Always verify threshold voltage, reset polarity, output type, and timeout delay before substitution.
What is the quiescent current consumption of the LM809M3-4.63/NOPB?
The LM809M3-4.63/NOPB draws a typical quiescent current of 14µA, making it suitable for battery-powered applications where power efficiency is critical. The device operates over a VCC range of 1.0V to 5.5V, providing flexible integration with 3.3V and 5V systems.
