The TLE92108 is a family of multi-MOSFET driver ICs, designed to control up to eight half-bridges (up to 16 n-channel MOSFETs) with one packaged device. A 24-bit Serial Parallel Interface (SPI) enables configuration of the TLE92108 and is used to control the half-bridges. The SPI offers a wide range of diagnostic features such as the monitoring of the supply voltage, the charge pump voltage, temperature warning, and over-temperature shutdown.


Key features

  • 8-fold Halfbridge (16 N-channel) MOSFET Driver Outputs
  • 3 PWM Iputs
  • Adaptive Multi-stage MOSFET Gate Control
  • Integrated Dual Stage Charge Pump Supporting an External N-FET

 

Additional features:

  • 24-bit Serial Peripheral Interface 
  • 2 x flexible current-sense amplifiers (for HS, LS and in phase) 
  • Detailed off-state diagnostic as open load, short circuit to the battery or to the ground) 
  • Drain-source monitoring for hard short circuit detection 
  • Current sense monitoring for soft short circuit detection 
  • Overtemperature warning and shutdown 
  • Timeout watchdog 
  • Configurable motor brake mode also in sleep mode
  • Low current consumption in sleep mode (3 µA)


Applications

  • Seat Module
  • Extended Functions (Steering - Gas Pedal Adjustment)
  • Central Door Lock
  • Body control module
  • Enclosure Systems (Trunk Opener, Sun-roof...)
