Summary
Current Limiting Power Switch with Current Limiter Sense Flag April 1994
Description
The CA3274 is a controlled current switch and may be used in general purpose switching applications that require specified maximum levels of current. The functional block diagram of the CA3274 is shown and a typical application circuit is shown in Figure 1. An internal emitter follower has 200mA of source drive output capability. The Control Input is a Schmitt trigger buffer amplifier for noise immunity in the environments typical of industrial and automotive control systems.
