... AC and DC motors and resis- tive loads such as incandescent lamps and other power drivers. Each output is an open collector protected power transistor driver. The CA3292A is similar to the CA3272A, except for an added collector-to-base Zener diode that provides over-voltage clamping protection on each power switching output. The ...

... CA3292A: Outputs limited to the V CLAMP 8. The single pulse clamp energy rating for the CA3292A is defined over a range of operating conditions. The Clamp Energy is a function of the Load Inductance, Load Resistance, Clamp Voltage, Supply Voltage, the Saturated ON Resistance (V Load Current at the instant of Turn-OFF. Refer to Figure 5 for the Safe Operating Area when driving inductive loads. Rating limits for Energy vs Single Pulse Width Time are plotted for different coil values ...

... CURRENT SOURCE INPUT ENABLE FIGURE 1. SCHEMATIC OF ONE INPUT STAGE As noted in the Block Diagrams, the CA3292A is equivalent to the CA3272A except that it has internal clamp diodes on the outputs to handle inductive switching pulses from the output load. The structure of each CA3292A output includes a Zener diode from collector-to-base of the output transistor. ...
