The SGM41296 is an I2C programmable monolithic driver with integrated power MOSFETs for thermoelectric cooling devices (TEC). It can deliver 1.5A to the TEC continuously, from a 2.7V to 5.5V source over the TEC operating voltage range. The TEC voltage is linearly controlled by an analog input voltage (CTL).
The voltage and current limits for protecting the TEC and the device can be adjusted, activated or deactivated on the fly by the 1Mbps I2C serial interface. A full suite of protection features such as over-current, over-voltage and over-temperature, and an internal 2 stage soft-start circuit are also provided by this device.
Requiring a minimal number of external components and with a tiny TQFN package, the SGM41296 offers the minimum solution size for TEC applications. It is an ideal choice for applications such as optical laser diode and fiber communication networks.
