Operating states State Description No supply Supply voltages on SUPIC and SUPHV are too low to provide any functionality. Undervoltage protection (UVP-supplies; see Section 7.9) is active when VSUPHV <Vrst(SUPHV) and VSUPIC <Vrst(SUPIC). The IC is reset. Disabled IC IC is completely disabled because pin SSHBC/EN is LOW. Thermal hold Activated as long as OTP is active. IC is not operating. PFC and HBC controllers are disabled and CSUPIC and CSUPREG are not charged. SUPIC charge IC supply capacitor (CSUPIC) is charged by HV start-up source. CSUPREG is not charged. SUPREG charge Stabilized supply capacitor (CSUPREG) is charged by series regulator. |
