When the CD– bq29400: 4.35V ±25 mV pin voltage reaches 1.2V, the OUT pin changes from low leveltoa high level.– bq29400A: 4.40V ±25 mV bq29401: 4.45V ±25 mV bq29405: 4.65V ±25 mV Prefixed Protection Threshold Voltage Programmable Delay Time High Power Supply Ripple Rejection Stable During Pulse Charge Operation 2nd Level Protectionin Lion Battery Packsin Notebook PCs Portable Instrumentation Medical and Test Equipment
The bq29400, bq29400A, bq29401, and bq29405 are
BiCMOS secondary protection ICs for 2-, 3-,or 4-cell
Lithium-Ion battery packs that incorporate a
high-accuracy precision over voltage detection circuit.
They includea programmable delay circuit for over
voltage detection time.
