Typical Application Circuit Voltage range 7V to 28V (42V peak), Limited down to 5V for start-stop systems Sleep mode current 20µA typically Microcontroller supply 3.3V or 5V, up to 70mA, > 70mA with external boost transistor Adjustable watchdog and reset generation Smart wake-up via BUS interface or KL15 Dead time generation (dynamical change) Motor current measurement amplifier Over current switch-off (dynamical change) FET short circuit protections (dynamical change) Configurable voltage monitoring LIN2.x transceiver, compatible down to LIN1.3 PWM interface, bidirectional with error feedback End-of-line high-speed flashing via LIN QFN package -40°C to +150°C junction (+170°C peak) BLDC(EC) motor control, multiple DC motor control Fuel, hydraulic, oil and water pumps Cooling fans, HVAC fans, positioning systems Turbo charger adjustment General Description The IC is a system base chip for driving BLDC and DC motors in B6, full bridge or half bridge applications. The IC ensures a safe, autonomous start-up and wake-up. It is suitable for high temperature applications. An integrated linear regulator supplies an external microcontroller. The supply output cur - rent can be “boosted” with an external transistor. For control- ling the motor, six power FET gate drivers with dynamically programmable, very precise dead time generation are imple- mented. Versions driving two half bridges only are available. Measurement functions for motor current, battery voltage and temperature are implemented. The IC has integrated programmable safety functions on mo- tor over current, battery over and under voltage, over temper- ature and short circuits at all six power FETs. Two product ver- sions with a “state of the art” LIN2.2A or bidirectional PWM interface are available. The LIN interface supports flash mode to upload a new firmware to the microcontroller.
