High reliability in automotive applications
The BD783xxEFJ-M series is qualified according to AEC-Q100 and supports a maximum operating temperature of 105°C. The use of a power package reduces heat generation at high volumes. This enables stable audio output even under difficult conditions without compromising functionality. In addition to overcurrent protection, a thermal shutdown and an undervoltage lockout circuit are integrated. These prevent damage caused by unusual heat generation and unexpected pops/cracking noises in the event of battery failure.
Rohm's BD783xxEFJ-M series loudspeaker operational amplifiers are installed on Cypress Semiconductor's Traveo-S6J3360 MCU family evaluation board for automotive applications. This allows easy evaluation under conditions similar to real-world cases.
