¨
¨
In normal state and standby mode
-
Charge pump circuit is in off state
-
Oscillator circuit is in off state
-
Standby current is below 2mA
-
For HT6751A, the oscillator circuit and charge
pump circuit is on until IN1 or IN2 or IN3 is low input
-
For HT6751B, the oscillator circuit and charge
pump circuit is on until IN1 or IN2 or IN3 is high input
The system enters thermal shutdown mode (current
is limited below 500mA) when the temperature of the
internal sensor is greater than Junction Temperature
and then release this mode until the temperature of
the internal sensor below (Junction Temperatue
>150°C). The system can accept IN1/IN2/IN3 signal
when in thermal shutdown mode.
