BQ24401 nimh / nicd smart battery charger ic qty:2
Switch-Mode Nickel Metal Hydride / NiCd battery charge controller.
3 status LEDs indicate charge state.
Safe management of fast charge for NiCd and NiMH
_ High-frequency switching controller for efficient and simple charger design
_ Pre-charge qualification for detecting shorted, damaged, or overheated cells
_ Fast-charge termination by dT/dt maximum temperature, and maximum charge time
_ Selectable top-off mode for achieving maximum capacity in NiMH batteries
_ Programmable trickle-charge mode for reviving deeply discharged batteries and for postcharge maintenance
_ Built-in battery removal and insertion detection
_ Sleep mode for low power consumption General Description The bq24401 is a programmable, monolithic IC for fast-charge management of nickel cadmium (NiCd) and nickel metal-hydride (NiMH).
Depending on the chemistry, the bq24401 provides a number of charge termination criteria:
_ Rate of temperature rise, dT/dt (for NiCd and NiMH)
