Each Power Driver has four inverting switches consisting of a non-inverting logic input stage and an inverting low-side driver output stage. All inputs are 5V TTL/CMOS logic compatible and have a common Enable input. Each output device has independent current limiting (ILIM) and thermal limiting (TLIM) for protection from over-load conditions. Steering diodes connected from each output (in pairs) to the Clamp pins may be used in conjunction with external zener diodes to protect the IC against over-voltage transients that result from inductive load switching. To allow for maximum heat transfer from the chip, all ground pins on the DIP, PLCC and SOIC packages are directly connected to the mounting pad of the chip. Integral heat spreading lead frames directly connect the bond pads and ground leads to conduct heat from the chip junction to the PC Board for good heat dissipation. The CA3262 and CA3262A can drive four incandescent lamp loads without modulating their brilliance when the “cold” lamps are energized. Outputs may be parallel connected to drive high current loads. The maximum output current of each output is determined by the over-current lim- iting threshold which is typically 1.2A but may be as low as 0.7A. Pinouts Ordering Information PART NUMBER TEMP.
