Protection Circuit
Undervoltage
protection
for V₆ : voltage at
pin 5 = V_{5 min}
if V₆ < V_{5 min}
V_{6 min}
Undervoltage
protection for V₆ :
voltage at
pin 5 = V_{5 min}
if V₆ > V_{6 max}
V_{6 max}
Undervoltage
protection for V_AC :
voltage at
pin 4 = V_{5 min}
if V₃ < V_3A
V_3A
Over temperature at
the given chip
temperature the IC
will switch V₅ toV_{5 min} T_j
Voltage at pin 3 if one
of the protection
function was
triggered;
(V₃ will be clamped
until V₆ < V_6A)
