The headlamp combines high beam, low beam, Daytime Running Lamp (DRL) and turn indicator. High beam and low beam could both adopt MBI6671 which features:
1. Simple and flexible circuit design
2. Support BOOST, BUCK, BUCK-BOOST and SEPIC
3. External MOSFET for flexible component selection/heat dissipation and driving higher output power
The DRL application can use MBI1841, which contains 8 linear channels. For each channel, the maximum current can be up to 150mA. Also, in order to decrease the cost of manpower for the driver board design, it has built-in multiple rolling patterns that do not require any additional coding, yet still achieve effects by setting up external resistors.
● LED Open/Short Circuit Protection
The protection helps to detect LED problems before the shipment and reduce the recall cost.
● High Efficiency
Also, MBI1841 can support up to high efficient parallel LED connections and quick altering DRL and position lamp brightness level. When it comes to turn indicators, MBI1841 represents a high efficiency (>80%) linear solution and has built-in patterns that allow speedy hardware settings. It helps decrease the complexity of circuit design.
● Pass AEC-Q100
AEC-Q100 Grade 1 certified.
