bq77915 3-5S Low Power Protector Evaluation Module
CAUTION
The circuit module may be damaged by overtemperature. To avoid damage,
monitor the temperature during evaluation and provide cooling, as needed, for
your system environment.
CAUTION
Some power supplies can be damaged by application of external voltages. If
using more than one power supply, check your equipment requirements and
use blocking diodes or other isolation techniques, as needed, to prevent
damage to your equipment.
CAUTION
The circuit module is not a finished product or electrical appliance. It must be
used by qualified personnel with additional equipment for evaluation only. Do
not leave EVM powered when unattended.
2.2
Items Needed for EVM Quick Start Evaluation
•
A bq77915 circuit module
•
An adjustable DC power supply that can provide 10 V to 22 V and 1 A minimum (a voltage range,
bipolar operation, and constant current – constant voltage capability is desirable)
•
Five resistors for cell voltage simulation such as 200
Ω
, 1% 1/4-W or other suitable value
•
A load such as a 5-k
Ω
, 1/4-W or other suitable resistor
•
A DC meter or measurement instrument
•
Some suitable cables for connection
