MIC5021 4.0 PIN DESCRIPTIONS The descriptions of the pins are listed in Table 4-1. TABLE 4-1: PIN FUNCTION TABLE Pin Number Pin Name 1 VDD 2 INPUT Description Supply (+12V to 36V). Decouple with ≥ 10 μF capacitor. TTL-Compatible Input. Logic high turns the external MOSFET on. An internal pull-down returns an open pin logic low. Retry Timing Capacitor. Controls the off time (tG(OFF) of the overcurrent retry cycle (duty cycle adjustment): Open = Approximately 20% duty cycle. Capacitor-to-Ground = Approximately 20% to
