Infineon TLE92108 multi-MOSFET driver family

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...)
