Introduction
BD81A74EFV-M / BD81A74MUV-M is a white LED driver capable of withstanding high input voltages (up to 35 V). The driver integrates a 4-channel constant-current driver on a single chip, with each channel capable of driving up to 120 mA (maximum), suitable for high-brightness LED driving. A buck-boost current-mode DC/DC converter is also built in to ensure stable operation during supply voltage fluctuations. Dimming is supported via PWM input (10,000:1 @ 100 Hz dimming capability).
Features
- AEC-Q100 compliant*1
- 4-channel current driver for LED driving
- Buck-boost current mode DC/DC converter
- DC/DC converter oscillation frequency control via external sync signal
- Spread spectrum function
- LSI protection functions (UVLO, OVP, thermal shutdown, OCP, short-circuit protection)
- LED fault detection (open/short circuit)
- VOUT discharge function (buck-boost topology limitation)
Applications
- Automotive central information display panels
- In-vehicle navigation systems
- Instrument clusters
- Head-up displays
- Small to medium-sized automotive LCD panels
