The Industry's First 6ch Power Management LSI for Li-ion Devices
03.15.07
ROHM has recently completed development of the industry's first 6ch Power Management LSI integrating a protective function and startup sequence into a single chip. The BD8611EFV ensures high reliability by protecting the system from various power supply failures common in set systems-specifically in battery-driven equipment including portable DVD players and navigation systems.
Integrating a startup sequence is absolutely essential for multi-block circuits and processor cores such as DSP and I/O which require different voltages (1.8V I/O, 3.3V DSP core) and sensitive power-up timing sequences. The BD9611EFV significantly reduces power system development while improving system reliability.
Applications:
- Portable DVD players
- Portable Navigation systems
- Portable Laptop
- PCs Portable
- Lithium ion devices
Features:
- Integrated protection function for all output power supplies
- Built-in switching path function for power supply
- Detects irregular outputs (rise or drop in supply voltage output, faulty startup sequence, overcurrent, or disconnection)
- Built-in startup sequence circuit
- Equipped with 6ch variable power supply (adjusted via external resistors) - ideal for portable equipment
- Two-cell lithium-ion battery charging function
