Application Circuits
HT6751A/B
4
August 7, 2000
In normal state and standby mode
–
Charge pump circuit is in off state
–
Oscillator circuit is in off state
–
Standby current is below 2 A
–
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 tempera-
ture of the internal sensor below (Junction
Temperatue >150 C). The system can ac-
cept IN1/IN2/IN3 signal when in thermal
shutdown mode.
