What are the key features of LM26CIM5X-RPA/NOPB?
- Factory-preset trip-point thermostat with ±4 °C maximum accuracy eliminates external resistors and trimming, reducing BOM count and calibration cost in thermal protection circuits
- Ultra-low maximum operating current of 40 µA makes it suitable for always-on thermal monitoring in battery-powered devices and energy-harvesting systems
- CMOS-compatible output in a compact 5-pin SOT-23 (2.9 mm × 1.6 mm body) enables direct interfacing with microcontroller GPIO or logic gates without level shifting
What is LM26CIM5X-RPA/NOPB used for?
The LM26CIM5X-RPA/NOPB is used in battery management and lithium-ion charging circuits to trigger over-temperature cutoff without a microcontroller, using its factory-preset thermostat threshold and CMOS-compatible output. Portable consumer electronics and wearables rely on its 40 µA maximum current draw for continuous thermal monitoring without meaningful battery drain. Industrial power-supply designers place it on heat sinks and transformer cores to activate cooling fans or shutdown relays when temperatures exceed the preset limit.

Frequently Asked Questions
What is the temperature accuracy of the LM26CIM5X-RPA/NOPB, and why does factory presetting matter for system design?
The LM26CIM5X-RPA/NOPB specifies a maximum temperature accuracy of ±4 °C across its operating range. Factory presetting means no external resistors or trimming potentiometers are needed to set the trip point, reducing component count by 2 to 4 parts per circuit and eliminating production calibration steps in high-volume thermal protection assemblies.
How does the 40 µA maximum operating current of the LM26CIM5X-RPA/NOPB benefit battery-powered designs?
With a maximum operating current of 40 µA from a typical 3.3 V supply, the LM26CIM5X-RPA/NOPB dissipates under 132 µW continuously. In a wearable device powered by a 100 mAh battery, this draws less than 0.04% of capacity per hour, enabling always-on thermal monitoring with negligible impact on battery runtime.
What package does the LM26CIM5X-RPA/NOPB use, and how compact is it for space-constrained PCB layouts?
It is housed in a 5-pin SOT-23 package with a body length of 2.9 mm, width of 1.6 mm, and height of 1.45 mm. This footprint is small enough to mount directly adjacent to a battery cell, Li-ion charging IC, or power MOSFET on a PCB where thermal sensing must occur within 5 mm of the heat source.
Is the LM26CIM5X-RPA/NOPB output compatible with microcontroller GPIO, and what logic family does it support?
Yes, the LM26CIM5X-RPA/NOPB has a CMOS-compatible output. It interfaces directly with 3.3 V and 5 V GPIO inputs on microcontrollers and FPGAs without a pull-up resistor in most configurations. The JESD-609 code e3 confirms RoHS-compliant lead-free construction for modern SMT reflow assembly processes.
