48V Cooling Fan
With the advent of mild hybrid engines and the incorporation of the 48V vehicle bus, many electrical systems within the vehicle will utilize this higher voltage bus for more efficient operation. One such application is the engine cooling fan. Microchip offers several components with key features that can help you design a complete, cost-effective, reliable and efficient system.
From dsPIC® digital signal controllers for motor control applications to high-voltage MOSFET drivers and various other components rated for high-temperature (150°C) operation, Microchip offers all the elements necessary for a complete embedded control system. And to aid in your development, the motorBench™ Development Suite helps to get your motor up and running quickly by performing accurate measurements of critical motor parameters and tuning feedback control gains.
Digital Signal Controllers
Several key features of the dsPIC Digital Signal Controllers from Microchip make them ideal for motor control applications. With an integrated digital signal processor, a single-cycle 16 X 16 MAC and 40-bit accumulators, along with Core Independent Peripherals (CIPs) that offload several functions from the CPU, the dsPIC is an excellent choice for math-intensive applications such as motor control applications.
- dsPIC33EP128MC502 – 16-bit digital signal controller with high-speed PWM, op amps and advanced analog
- dsPIC33EV256GM003 – 16-bit, 5V digital signal controller with PWM, SENT, op amps and advanced analog
- dsPIC33CK64MP508 – 16-bit digital signal controller with high-resolution PWM and CAN FD
Three Phase MOSFET Drivers
For ease of design, an integrated MOSFET driver provides an interface between the digital signal controller and the six MOSFET array controlling the three-phase motor. These devices feature low propagation delays, anti-shoot through outputs which are guaranteed to not overlap, and an overcurrent protection and an internal diode that charges the high-side gate drive bootstrap capacitor.
- MIC4607 – 85V, three-phase MOSFET driver with adaptive dead-time, anti-shoot-through and overcurrent protection
The Microchip lineup of LIN transceiver products range from standalone to LIN transceivers to fully integrated System-in-Packages (SIPs) that include a voltage regulator and a microcontroller. Our LIN transceivers are compliant with the industry-standard LIN bus specifications and are approved by the major global OEMs.

Our basic power management solutions include several automotive grade linear and switched voltage regulators. Linear regulators feature low dropout voltages, ultra-low quiescent currents, wide input voltage ranges, load dump and reverse batter protection. Switching regulators support buck, boost, buck-boost and SEPIC designs from 100 mA to 12A output currents.
- MAQ5280 – High-performance, low dropout regulator, 25 mA, 120V, adjustable Vout from 1.215 to 5V.
- MCP1790 – 30V, 70 mA, load dump protected linear voltage regulator
- MCP16311 – 30V, 1A PFM/PWM high-efficiency synchronous buck regulator
- MCP16331 – 50V 1A non-synchronous buck regulator
Microchip’s portfolio of Operational Amplifiers (Op Amps) include general purpose, precision and zero-drift amplifiers. If your design requires low offset voltages or drift, low quiescent currents or enhanced EMI rejection, we have a solution that fits your needs. Our op amps are available in single-, dual- and quad-configurations in very small form factors.
- MCP6004 – General purpose quad op amp, 1MHz, low power, rail-to-rail
- MCP6032 – High-precision dual op amp, 0.9 µA quiescent current, 150 µV offset voltage
