The UC3909 family of Switchmode Lead-Acid Battery Chargers accurately controls lead acid battery charging with a highly efficient average current mode control loop. This chip combines charge state logic with average current PWM control circuitry. Charge state logic commands current or voltage control depending on the charge state. The chip includes undervolt.
• Accurate and Efficient Control of
Battery Charging
• Average Current Mode Control from Trickle to Overcharge
• Resistor Programmable Charge Currents
• Thermistor Interface Tracks Battery Requirements Over Temperature
• Output Status Bits Report on Four Internal Charge States
• Undervoltage Lockout Monitors VCC and VREF
