Addressing the Challenges of Automotive Power Supply:
The growing trend of electrification in the automotive industry demands robust power delivery solutions for ECUs and other electronic components. These components require LDO regulators that can efficiently step down the vehicle's battery voltage while maintaining stable operation under challenging conditions:
- Sudden Voltage Fluctuations: Automotive power supplies are susceptible to sudden voltage fluctuations from the lead-acid battery. The BD9xxM5-C series features excellent line-transient response to ensure consistent power delivery even during voltage spikes.
- Varying Load Currents: ECUs and other downstream devices experience fluctuations in load current during operation. The BD9xxM5-C series boasts exceptional load-transient response characteristics, enabling rapid voltage recovery and stable operation.
Unveiling QuiCur Technology for Superior Performance:
ROHM's proprietary QuiCur high-speed load response technology sets the BD9xxM5-C series apart. QuiCur delivers unparalleled performance:
- Exceptional Load Response: Even with rapid load changes (0 to 500mA in 1 μs), the LDO maintains output voltage within just 100 mV of the set voltage, ensuring consistent power delivery for sensitive electronic components.
- Low Current Consumption: The BD9xxM5-C series boasts low typical current consumption of 9.5 μA, contributing to lower overall power consumption in automotive applications.
Flexibility and Reliability for Diverse Applications:
The BD9xxM5-C series caters to a wide range of automotive power needs with its versatility:
- Multiple Package Options: Available in four package options – compact HTSOP-J8, high heat dissipation TO252 (TO252-3/TO252-5), and HRP5 – users can select the ideal package size based on their specific application requirements.
- AEC-Q100 Compliance: Meeting the stringent AEC-Q100 automotive reliability standard, the BD9xxM5-C series guarantees exceptional performance and durability in harsh automotive environments.
- Wide Product Lineup: With 18 models planned by FY2024, including TO252-3, TO252-5, and HRP5 package options, ROHM offers a comprehensive solution for diverse automotive power needs.
Suitable Applications:
The BD9xxM5-C series is ideal for a wide range of automotive applications, including:
- ECUs (Engine Control Units, Body Control Modules, etc.)
- Powertrain Systems (Fuel Injection, Tire Pressure Monitoring Systems)
- Body Systems (Body Control Modules)
- Infotainment Systems (Instrument Clusters, Head-Up Displays)
