DESCRIPTIONThe L9484 is a monolithic multifunction generator
Voltage regulator intended for use in automotive
charging applications.
This All Silicon Voltage Regulator regulates the out-
put of an automotive generator by controlling the field
winding current by means of a variable frequency
PWM high side driver.

L9473Notes:1. The Field Drive capability shall not decrease as a function of temperature between 25°C and 150°C, at a rate faster than -0.024A/
°C (for example, Field Drive shall be capable of ≥7.2A at 100°C).

Table 6. DIAGNOSTIC (Tcase = -35°C to +150°C unless otherwise specified) This condition can happen when the connection between the battery and VGO or the output terminal of the generator is broken.
The 1.1 second delay is not required, and current is sinked by ASVR. When no fault is detected the Lamp terminal is pulled up by ASVR.
