Frequently Asked Questions
What reset threshold voltage does the LM3722IM5-3.08 use and how is it set?
The LM3722IM5-3.08 has a fixed reset threshold of 3.08 V, which is factory-programmed and cannot be adjusted externally. When the monitored supply voltage drops below 3.08 V, the device asserts its reset output, holding the connected microprocessor in reset state until the supply recovers and the timeout period expires. This fixed threshold simplifies design by eliminating external resistor dividers needed by adjustable threshold devices.
How does the LM3722IM5-3.08 protect microprocessors during power-up and brownout conditions?
The LM3722IM5-3.08 monitors the supply voltage and asserts a reset signal whenever the voltage is below 3.08 V, including during power-up ramp and supply droops caused by heavy load transients. This ensures the microprocessor remains in a defined reset state until the supply stabilizes, preventing corrupted code execution or peripheral misinitialization. The device provides a timeout delay after the supply crosses the threshold before releasing reset, typically in the range of 100 ms to 400 ms depending on variant.
Which microcontroller supply rails is the LM3722IM5-3.08 best matched to supervise?
The LM3722IM5-3.08 with its 3.08 V threshold is optimally matched to supervise 3.3 V supply rails used by ARM Cortex-M, PIC, and AVR microcontrollers. The 3.08 V threshold provides approximately 220 mV of headroom below the nominal 3.3 V rail, detecting brownout conditions before processor operation becomes unreliable. Systems running 5 V microcontrollers should use a higher-threshold variant, while 1.8 V MCU designs require a different LM3722 configuration.
What package does the LM3722IM5-3.08 come in and how small is its PCB footprint?
The LM3722IM5-3.08 is packaged in a 5-pin SOT-23 (TSOP5) with a footprint of approximately 2.9 mm x 1.6 mm and typical body height of 1.45 mm. This compact package is one of the smallest available for supervisor ICs, making it ideal for handheld, wearable, and IoT edge node designs where board space is at a premium. The 5-pin SOT-23 uses standard 0.95 mm pin pitch and is fully compatible with automated SMT assembly processes.
