Leckerkennungs-IC für Automobile BD9582F-M

Leakage Detection IC for Automotive BD9582F-M

Overview | Highlight 1 | Highlight 2 Applications | Lineup


In recent years, with the increased proliferation of electric and hybrid vehicles comes a demand for 100V AC outlets for powering consumer electronics/appliances and to act as an emergency power source. With a guaranteed operating range up to 105C, the BD9582F-M is the industry's first*1 leakage detection IC specifically designed for AC outlets in automotive systems (i.e. AC inverters). In addition, ultra-low current operation reduces battery consumption considerably.

Highlight 1: Supports operating temperatures up to 105C (automotive-grade)

Supports operating temperatures up to 105C (automotive-grade)

The BD9582F-M features an operating temperature range of -40C to +105C, implements electromagnetic countermeasures, and complies with reliability test certification standards for automotive ICs, providing the necessary reliability for automotive applications.


Highlight 2: Industry-low current consumption

Circuit optimization results in the industry's lowest current consumption (330uA typ.), contributing to significantly lower battery consumption in circuit breakers and other sets designed for continuous operation.

Industry-low current consumption


Ideal for AC inverters and charging equipment in electric and hybrid vehicles. Also suitable for standard circuit breakers and leakage relays.
