Typical Applications
LM26CIM5X-YPE/NOPB is suitable for 6 applications: Over-Temperature Protection for Power Supplies, Battery Charger Thermal Protection, Motor Controller Over-Temperature Protection, Industrial Equipment Over-Temperature Alarm, Automotive Electronics Thermal Protection, Consumer Electronics Over-Temperature Protection.
Over-Temperature Protection for Power Supplies
The LM26CIM5X-YPE/NOPB is ideal for monitoring the temperature of power supply components such as MOSFETs, diodes, and transformers. Its 115°C trip point ensures that these components are shut down before they exceed safe operating temperatures. The active-low open-drain output can directly drive a shutdown pin on a PWM controller or a logic gate to disable the supply. With ±3°C accuracy and a low supply current of 40µA, it adds minimal power overhead. The SOT-23-5 package allows placement close to the heat source for accurate sensing. In a typical design, the output is pulled up to the logic rail with a 10kΩ resistor and connected to an enable pin. This provides a simple, reliable thermal protection solution without the need for a microcontroller.

Battery Charger Thermal Protection
In battery charging applications, the LM26CIM5X-YPE/NOPB monitors the temperature of the charging circuit or the battery pack itself. The 115°C trip point is suitable for protecting lithium-ion batteries from thermal runaway. The open-drain output can be connected to the charger's enable pin to halt charging when the temperature exceeds the threshold. The device's low power consumption is beneficial for portable devices, as it does not significantly drain the battery. The small SOT-23-5 package fits easily on a charger PCB. With ±3°C accuracy, it provides reliable protection. The hysteresis of 10°C prevents rapid on/off cycling, ensuring stable operation. This thermostat can be used in conjunction with a battery management IC to provide an additional layer of safety.

Motor Controller Over-Temperature Protection
Motor controllers often generate significant heat due to high currents. The LM26CIM5X-YPE/NOPB can be mounted on the heatsink or near the power stage to monitor temperature. When the temperature exceeds 115°C, the output goes low, signaling the microcontroller to reduce motor current or shut down the driver. The open-drain output is compatible with logic-level inputs. The device's wide supply voltage range (2.7V to 5.5V) allows it to be powered from the same rail as the motor driver. The small package is easy to place in tight layouts. With ±3°C accuracy, it ensures the motor driver is protected from overheating. The low supply current minimizes self-heating, preserving accuracy. This thermostat is a cost-effective solution for thermal management in motor control applications.

Industrial Equipment Over-Temperature Alarm
In industrial equipment, the LM26CIM5X-YPE/NOPB can be used to trigger an alarm or shut down machinery when the temperature exceeds 115°C. The active-low output can drive a buzzer, LED, or relay through a transistor. The device's operating temperature range of -55°C to +125°C makes it suitable for harsh environments. The SOT-23-5 package is robust and reliable. With ±3°C accuracy, it provides precise temperature monitoring. The low supply current is advantageous for always-on monitoring. The open-drain output allows easy interfacing with PLCs or microcontrollers. This thermostat can be used in motor control cabinets, power distribution units, and other industrial systems to prevent overheating and equipment damage.

Key Differentiators
- Factory-preset trip point at 115°C (vs TMP302BDRLR)
- Wide supply voltage range (2.7V to 5.5V) (vs ADT6401SRJZ-RL7)
- Small SOT-23-5 package (vs ADT6401SRJZ-RL7)
Design Notes
Place a 0.1µF ceramic capacitor close to the V+ pin to decouple the supply. The open-drain output requires an external pull-up resistor, typically 10kΩ, to V+ or the logic supply. Ensure the pull-up voltage does not exceed the absolute maximum rating of the output pin.
For accurate temperature sensing, mount the LM26CIM5X-YPE/NOPB close to the heat source and ensure good thermal contact via PCB copper. Avoid placing it near other heat-generating components that could cause false trips. The device's low supply current minimizes self-heating, but proper layout is still essential.
Do not leave the open-drain output floating; always use a pull-up resistor. Also, ensure the supply voltage is within the specified range (2.7V to 5.5V) to avoid incorrect operation. The trip point is fixed at 115°C, so verify that this is suitable for your application before design-in.
