The AIC1508 is a rigid, low-cost general purpose high voltage driver IC with 8 high voltage push-pull outputs. The device has been designed for harsh industrial applications and allows a wide application area. The outputs can drive capacitive and resistive loads such as piezoelectric transducers, electroluminescent devices and micro-mechanical actuators. The maximum operating voltage is 300V, and each output has a source-sink capability of up to 40mA.
External output resistors can be used to limit the maximum power dissipation of the device, allowing the outputs to be run in parallel. The IC also allows the use of an external resistor to set the switch-on time of the outputs. The IC provides protected direct transistor gate inputs. The high voltage push-pull outputs are well protected against possible latch-up by using the bulk-drain diodes of the output MOSFETs and their full dielectric isolation.
