NCS35011 Evaluation Board User's Manual
NCS35011EVK
Introduction
This user's manual provides information regarding the
configuration and method to test the NCS35011 IC. The
evaluation board serves as a demonstration of NCS35011
general functionality. NCS35011 manages lithium−ion
batteries from 3 to 5 cells in series with accurate battery
indication through 3 to 5 LED outputs. Each cell in the
battery pack is monitored for an over−voltage (OV) and

under−voltage (UV) condition. Upon detecting an
over−voltage, the ODI pin will assert indicating a fault
condition and stay asserted until the fault is cleared. During
an under voltage condition, the UDI pin will also assert
indicating the fault but will have a pulse width that is pre−set
in the protector. Both OV and UV detections have a hard
coded pre−set delay time before fault indication.
Quick Start
Recommended Setup
Before beginning, the following setup is needed:
•
DC power supplies to generate the battery cell voltages.
•
A single DC power supply and five SMD (Rt1−Rt5) or
external test resistors to generate the voltage divided
cell voltages.
•
Two external Pull−up resistors for UDI and ODI pin
open−drain configuration test.
•
Function generator to generate the cell level over
voltage or under voltage.
•
Oscilloscope.
•
Digital Multi−meter.
