LN8953
Description
LN 8953 is a highly integrated, low cost, battery pack protection and monitor IC which features
Over Voltage (OV), Under Voltage (UV), Over Current (OC), Short Circuit (SC), Over Temperature (OT) protection functions for managing Li-Ion /Polymer, 3 cell battery packs for power-tools, notebook PC and UPS applications etc. LN8953’s over current protection has high accuracy voltage detection (±10m V). Thus LN8953 can use lower current-sense resistors (such as 2.5mΩ, 5mΩ) to reduce power dissipation and thermal issues while maintaining high accuracy current detection. LN8953 has three levels over-current protection using three, accurate integrated parators. These current parators provide accurate and timely protection, and avoid any unexpected false-trigger situations. LN8953 supports three modes for OC/SC release, i.e. Charger plugging-in Release, Load-open Release and Timer Release (optional). Timer Release delay time set shares with OV delay capacitor set.
