Overview

R5437L Series 1 to 3 Cells Li-Ion Battery Protection IC for Secondary Protection No.

EA-416-210518 OUTLINE The R5437L is an overcharge protection IC for 1 to 3 serial cells Li-ion / Li-polymer rechargeable battery.

This device provides the high-accuracy voltage detection function and the shutdown function can reduce the supply current to the minimum when all cell’s voltage becomes less than the shutdown detection voltage.

Key Features

  • High Voltage Tolerant Process Absolute Maximum Ratings.
  • 26 V.
  • Low Supply Current During Operation, Cell-voltage: 3.9 V, 3-Cells.
  • Typ. 0.85 µA.
  • High-accuracy Voltage Detection Overcharge Detector Threshold (VDET1n(1)).
