When the input voltage is below the positive trip point, the quiescent current of the supply voltage line is less than 1.0 µA, (typ). When the input voltage exceeds the positive trip point (1.45 V, typ), the input stage “wakes up” the rest of the CS8240 circuitry and turns on the output stage. Output Stage The output stage is built around a high current PNP output transistor. A control amplifier monitors the saturation voltage of the output PNP and maintains a balance of low saturation voltage and minimum base drive to the PNP for the given output current. The base drive of the PNP is the dominant component of the quiescent current of the CS8240 and is dependent on the level of output current. Short circuit protection (1.1 A, typ) is also incorporated in the output stage. Protection Circuitry In addition to the short circuit protection mentioned above, the CS8240 also incorporates a thermal shutdown circuit (165 °C, typ) and a high voltage shutdown circuit (33 V, typ), both of which cut off the drive to the PNP output transistor when excessive current is drawn. Inherent in the design of the CS8240 is transient protection to +60 V and –50 V on the supply line. The CS8240 is ESD protected in excess of 2.0 kV (Human Body Model). |
