General Description

The bq24401 is a programmable,

monolithic IC for fast-charge manage-

ment of nickel cadmium (NiCd) and

nickel metal-hydride (NiMH).

Depending on the chemistry, the

bq24401 provides a number of

charge termination criteria:

l

Rate of temperature rise, ∆T/∆t

(for NiCd and NiMH)

l

Maximum temperature

l

Maximum charge time

For safety, the bq24401 inhibits fast

charge until the battery voltage and

temperature are within user-defined

limits. If the battery voltage is below

the low-voltage threshold, the

bq24401 uses trickle-charge to

condition the battery. For NiMH

batteries, the bq24401 provides an

optional top-off charge to maximize

the battery capacity.

The integrated high-frequency com-

parator allows the bq24401 to be the

basis for a complete, high-efficiency

power-conversion circuit.
