LTC3305 – Lead Acid Battery Balancer


The LTC®3305 balances up to 4 lead acid batteries connected in series. All voltage monitoring, gate drive, and fault detection circuitry is integrated. The LTC3305 is designed for stand-alone operation and does not require any external control circuitry.

The LTC3305 employs an auxiliary battery or an alternative storage cell to transfer charge to or from each individual battery in the stack. A mode pin provides two operating modes, timer mode and continuous mode. In timer mode, once the balancing operation is completed, the LTC3305 goes into a low power state for a programmed time and then periodically rebalances the batteries. In continuous mode, the balancing operation continues even after the batteries are balanced to their programmed termination voltage.

Pencil balancer using Dynamic Vision Sensor

This robot is balancing a standard pencil based only on visual input from two “dynamic vision sensors”. These sensors do not rely on a constant background, as shown when rotating the platform during operation. To achieve the balance it uses two servo motors and two Dynamic Vision Sensors one for each axis. These sensors “watch” for changes in pixel contrast, outputting a positive or negative number based on the direction the pencil is beginning to fall. An NXP2103 running at 64 MHz reads in the values and drives the pair of servo motors accordingly. [via]
