Key Features
- Fixed 2.32V threshold voltage supervisor provides precise supply monitoring for microcontroller reset generation
- Single-channel, single-function design in a 5-pin SOT-23 package delivers the smallest possible PCB footprint
- No adjustable threshold components needed, simplifying BOM and reducing design effort for fixed-rail systems
Applications
The LM3722EM5-2.32 is used to supervise power supply rails in microcontroller and DSP-based systems, asserting a reset signal whenever the monitored voltage falls below the 2.32V threshold. It is well suited for battery-powered embedded systems, portable consumer electronics, and IoT devices that require reliable processor initialization after power-on or brownout events. Its tiny SOT-23 footprint makes it equally at home in space-constrained wearables and industrial control modules.

Frequently Asked Questions
What threshold voltage does the LM3722EM5-2.32 monitor?
The LM3722EM5-2.32 monitors a fixed 2.32V threshold. When the supervised supply drops below this level, the IC asserts a reset signal to prevent microcontrollers or processors from operating with an insufficient supply voltage.
Can the threshold of the LM3722EM5-2.32 be adjusted externally?
No, the LM3722EM5-2.32 has a non-adjustable fixed threshold of 2.32V. For applications requiring a different supervision voltage, Texas Instruments offers other LM3722 variants with different fixed thresholds.
What package does the LM3722EM5-2.32 come in?
The LM3722EM5-2.32 is packaged in a 5-pin SOT-23 (TSOP5) package, JESD-30 code R-PDSO-G5, measuring approximately 0.11 inches wide. This ultra-compact package is ideal for dense, space-constrained PCB designs.
How many channels does the LM3722EM5-2.32 supervise?
The LM3722EM5-2.32 supervises a single channel with one function — voltage monitoring and reset generation — making it a simple, dedicated solution for single-rail microcontroller or processor power supervision.
What applications is the LM3722EM5-2.32 best suited for?
The LM3722EM5-2.32 is ideal for microcontroller reset circuits in battery-powered IoT nodes, portable consumer electronics, and industrial control boards where a reliable 2.32V supply monitor in a minimal footprint is required.
