Infineon TLE94x03EP & TLE94x04EP half-bridge driver IC

The TLE94x03EP and TLE94x04EP are protected 3- and 4-fold half-bridge drivers designed for automotive motion control applications such as mirror x-y-adjustment and DC flap motors for Heating, Ventilation and Air Conditioning systems (HVAC). The devices are part of a family which includes also 6-, 8-, 10-, and 12fold half-bridge driver ICs. The devices can drive DC motor loads up to 0.9 A per half-bridge in cascaded or parallel operation. They offer diagnosis features such as short circuit, open load, power supply failure and over-temperature detection to ensure safe operation.

Key features

• 3- and 4-half-bridges with integrated output stages and PWM capability
• Very low power consumption in sleep mode
• 3.3V / 5V compatible inputs with hysteresis
• All outputs with overload and short circuit protection

Additional features

• Independently diagnosable outputs (overcurrent, open load)
• Open load diagnostics in ON-state for all high-side and low-side
• 16-bit Standard SPI interface with daisy chain and in-frame response capability / Direct interface for control and diagnosis
• Fast diagnosis with the global error flag
• Overtemperature pre-warning and protection
• Over- and Undervoltage lockout
• Cross-current protection
• Variable driving schemes for up to 3 motors
• Control and diagnosis of each output via SPI or DI
• Device operates down to 5.5V (supporting Start Stop system of fuel efficient vehicles)

Applications

• Small DC motors (up to 0.9A/half-bridge
• Mirror x-y-adjustment
• Flap motor for HVAC systems
• Bi-stable relays
