ML5232-001TDZ07GL

ML5232 is an overvoltage protection IC for 14-cell series-connected lithium-ion rechargeable battery packs. If an overvoltage condition is detected on any individual cell, it outputs an "L" level at the N-channel open-drain alarm output and an "H" level at the CMOS alarm output.

Applications

• Power tools and garden tools
• Cordless vacuum cleaners
• E-bikes and pedal-assist electric bicycles
• Uninterruptible Power Supplies (UPS)
• Energy Storage Systems (ESS)
