The device provides three half-bridge drivers each capable of driving a high-side and low-side N-channel MOSFET while also providing sophisticated protection and monitoring of the FETs. A charge-pump driver enables 100% duty cycle and supports low battery voltages during cold-crank operation. The integration of current-sense amplifiers, integrated phase comparators, and SPI-based configuration of the driver and its peripherals enable reduction of the bill of materials (BOM) and space on the printed circuit board (PCB) because of the elimination of most external and passive components. C device : Low-drift offset high-precision amplifiers – B Device: 2 current-shunt amplifiers and 3phase comparators with real-time monitor through digital pins 3-PWM or 6-PWM input control up to 20 kHz Single PWM-mode commutation capability Supports both 3.3-V and 5-V digital interface Serial peripheral interface (SPI) Thermally-enhanced 48-Pin HTQFP Protection features: – Internal regulators, battery voltage monitor – SPI CRC – Clock monitor – Analog built-in self test – Programmable dead-time control – MOSFET shoot-through prevention – MOSFET VDS overcurrent monitors – Gate-source voltage real time monitor – Overtemperature warning and Shutdown The DRV3245Q-Q1 device also integrates diagnostics and protection for each internal block and provides support for common system diagnostic checks each of which can be instantiated and reported through SPI. This flexibility of the integrated features allows the device to integrate seamlessly into a variety of safety architectures.

Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. 5.7 Glossary SLYZ022 — TI Glossary.
