ISL25700FRUZ-TK [INTERSIL]

The ISL25700 sets up and monitors temperature at the point of interest, compares it with the user programmable setpoint, and adjusts the output until the set temperature is reached. An external power MOSFET, a heater, an NTC thermistor and the ISL25700 are parts of the temperature control loop. It features programmable overcurrent protection of the MOSFET, which automatically adjusts output voltage to keep MOSFET power under user-defined limits. The device includes an additional 8-bit General Purpose DAC for application-specific use. It offers user-programmable setpoint via I2C, setpoint range from +40°C to +110°C, operational temperature range from -40°C to +125°C, 3°C initial setpoint accuracy, coarse and fine tuning control, ±0.5°C long-term drift, programmable current protection, 5-bit selectable gain control, wide power supply range (3V to 15V), compatibility with 20kΩ to 200kΩ NTC thermistors, and high reliability with 10,000 data changes per bit per register endurance and 10-year data retention at ≤+125°C.
