Features

  • Output Stage Consists of Eight Programmable Half-Bridge MOSFET Drivers
    (Configurable in Half, Full, or Parallel Bridges) Which Deliver Modulated
    Current to Each Coil
  • Linear Mode Output: Generates a Sine Wave Voltage That is Controlled
    by the Microcontroller
  • Output Stage is Overload Protected for Short and Over Temperature
  • Driver Control and Diagnosis Blocks Drive the Gates of the MOSFETS
    Via Data From the SPI
  • Antenna Diagnostics: Short to GND, Short to VBAT, And Open Load
    Via Current Measurement
  • Divider Block Generates an Internal Frequency From the Input Clock
    (Main Controller); Used for the Internal Logic
  • Sophisticated Failure Detection and Handling
  • HTSSOP (PWP) 28-Pin Package
  • Operating Temperature Range:
    –40°C to +105°C
  • APPLICATIONS
    • Automotive Passive Start and Passive Entry Applications
