Key Features
- Resistor-programmable trip-point allowing any temperature threshold to be set with a single external resistor, avoiding microcontroller firmware
- Open-drain output compatible with 1.8 V to 5.5 V logic systems, suitable for interrupt-driven fan control or system shutdown triggers
- Tiny 6-pin SOT-23 package (2.9 mm × 1.6 mm) minimizing board space in battery-powered and space-constrained thermal management designs
Applications
The MCP9510HT-E/CH is used in laptop cooling fan controllers, portable power bank thermal protection, and battery management systems where a simple analog trip-point eliminates the need for a microcontroller or firmware. Industrial motor drives and LED driver modules employ this temperature switch to assert a hardware fault signal when junction or ambient temperature exceeds a programmed threshold, protecting downstream components. Consumer appliances and IoT edge devices benefit from its single-resistor configuration, which sets the alert temperature anywhere within the -40°C to 125°C operating range with no software overhead.

Frequently Asked Questions
How is the temperature threshold of MCP9510HT-E/CH programmed, and what range of trip-points can be set?
The MCP9510HT-E/CH trip-point temperature is set by connecting a single external resistor between the RSET pin and ground. Resistor values from approximately 10 kΩ to 150 kΩ map to temperature thresholds across the -40°C to 125°C operating range, allowing designers to target any alert temperature without firmware or digital bus configuration.
What output voltage levels does MCP9510HT-E/CH support, and how does it interface with 1.8 V microcontrollers?
MCP9510HT-E/CH has an open-drain output compatible with logic supply voltages from 1.8 V to 5.5 V. A pull-up resistor of 10 kΩ to the microcontroller's 1.8 V or 3.3 V I/O supply is sufficient to interface the temperature alert output directly to a GPIO interrupt pin, enabling low-latency software response to overtemperature conditions.
How compact is MCP9510HT-E/CH, and what PCB area does it require in a wearable design?
The 6-pin SOT-23 package measures 2.9 mm × 1.6 mm with a 0.95 mm pin pitch, requiring a PCB land pattern under 5 mm². Combined with just one external resistor and a pull-up, the total solution footprint stays below 20 mm², making MCP9510HT-E/CH an excellent thermal protection choice for wearable health monitors and compact IoT nodes.
When should MCP9510HT-E/CH be preferred over a digital I2C temperature sensor with software thresholds?
MCP9510HT-E/CH is preferred when the design needs a hardware trip-point that triggers independently of processor state, such as during deep sleep or CPU lockup. Unlike I2C sensors that require periodic polling or interrupt registers, the MCP9510HT-E/CH asserts its output in under 150 ms of thermal response time, providing a reliable 125°C emergency shutdown signal with zero firmware dependency.
