DESCRIPTION  
The UC2909 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 undervoltage lockout circuitry to  
insure sufficient supply voltage is present before output switching starts. Additional circuit blocks include a  
differential current sense amplifier, a 1.5% voltage reference, a –3.9-mV/°C thermistor linearization circuit,  
voltage and current error amplifiers, a PWM oscillator, a PWM comparator, a PWM latch, charge state decode  
bits, and a 100-mA open collector output driver.
