Q & A
- What is the operating voltage range of the MC33886PVWR2?
The operating voltage range is from 5.0 V to 40 V, with derating of specifications above 28 V. - What is the RDS(on) of the H-Bridge MOSFETs in the MC33886PVWR2?
The RDS(on) of the H-Bridge MOSFETs is 120 mΩ. - Is the MC33886PVWR2 compatible with TTL and CMOS inputs?
Yes, the MC33886PVWR2 is TTL / CMOS compatible. - What is the maximum PWM frequency supported by the MC33886PVWR2?
The maximum PWM frequency supported is up to 10 kHz. - Does the MC33886PVWR2 have built-in current limiting and overtemperature protection?
Yes, it features active current limiting and overtemperature protection with latch-OFF. - How does the MC33886PVWR2 handle fault conditions?
Fault conditions such as undervoltage shutdown, output short-circuit latch-OFF, or overtemperature latch-OFF will cause the outputs to turn OFF and set the fault output flag Low. The fault flag can be cleared by toggling either of the Disable inputs or V+. - What is the package type and operating temperature range of the MC33886PVWR2?
The package type is 20-pin HSOP with an exposed pad, and the operating temperature range is -40 °C to 125 °C. - What are some common applications of the MC33886PVWR2?
Common applications include automotive systems, industrial and robotic DC motor control, marine systems, appliance actuators, powered tools, and antenna positioning systems. - How does the MC33886PVWR2 protect against short-circuit conditions?
The device uses a junction temperature-dependent active current “fold back” protection scheme, ramping down the current limited output as the junction temperature increases. - Does the MC33886PVWR2 have fault status reporting?
Yes, it has fault status reporting through an open-drain output requiring a pull-up resistor to 5.0 V.
