The Texas Instruments UC2909MDWREP is an integrated circuit designed for controlling lead-acid battery charging. It utilizes an efficient average current mode control loop combined with charge state logic to manage charging from trickle to overcharge.
Key features include resistor-programmable charge currents, a thermistor interface for tracking battery requirements over temperature, and output status bits reporting four internal charge states. The device operates with a supply voltage of up to 40V and has an operating temperature range of -55°C to 125°C.
This IC is housed in a 20-SOIC Surface Mount package, making it suitable for various electronic designs. It supports defense, aerospace, and medical applications, offering accurate and efficient battery control.
The UC2909-EP includes undervoltage lockout circuitry to ensure sufficient supply voltage before output switching begins. Additional circuit blocks include a differential current sense amplifier, a 1.5% voltage reference, and a PWM oscillator.
