48V Cooling Fan

Several key features of dsPIC DSCs make them ideal for motor control applications. Featuring an integrated Digital Signal Processor (DSP), a single-cycle 16 × 16 MAC and 40-bit accumulators, along with Core Independent Peripherals (CIPs) that offload several functions from the Central Processing Unit (CPU), dsPIC DSCs are excellent choices for math-intensive applications.

• dsPIC33EP128MC502 – 16-bit DSC with high-speed Pulse-Width Modulation (PWM), op amps and advanced analog
• dsPIC33EV256GM106 – 16-bit, 5V DSC with PWM, CAN, SENT, op amps and advanced analog
• dsPIC33CK256MP508 – 16-bit DSC with high-resolution PWM and CAN FD

For ease of design, an integrated MOSFET driver provides an interface between the DSC 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.

Our LIN transceivers range from stand-alone 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.

• MCP2003B – Stand-alone 8-pin LIN transceiver
• ATA663254 – LIN System Basis Chip including 5.0V voltage regulator and NRES output
• ATA663454 – LIN System Basis Chip including 5V voltage regulator, watchdog and high-side switch

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.

• MIC5280 – 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

Our portfolio of operational amplifiers (op amps) includes 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
• MCP6V28 – 620 µA, 2 MHz auto-zeroed op amp
