The SGM62138 is a wide input and output bi-directional 4-switch Buck-Boost controller. The device is capable to operate at 36V input and output, and withstands up to an absolute maximum of 40V. The device integrates four 2A drivers which is suitable for most common catalog MOSFETs. The boot diode is also integrated to reduce design complexity.
The bi-directional control of the SGM62138 enables easy implementation of battery charging and reverse OTG operations. While supporting charging Li-ion batteries up to 8 cells, the SGM62138 is also capable to program both input and output as constant voltage ports with dedicated constant current loop.
The SGM62138 integrates I2C bus to support communication between host processor and the DC/DC. Features such as output voltage slew rate, charging profile, constant current loop threshold, and direction control are adjustable via I2C.
Power path control is also available on SGM62138. Multi-input source control and VIN sinking device detections are implemented to reduce system design complexity.
The SGM62138 also integrates various protection features such as over-voltage protection, over-current protection, input under-voltage lockout, short-circuit protection and over-temperature protection.
The SGM62138 is available in a Green TQFN-4×4-32L package.
