IP9001
4-CH MOTOR DRIVE IC FOR PORTABLE CDP
APPLICATION SUMMARY (Continued)
5. Reset circuit
When the output voltage of the DC/DC converter reaches 90% of the VCC1,
then RESET goes from LOW to HIGH level and AMUTE goes from HIGH to LOW level.
Hysteresis voltage of each pin is 50mV
Figure3. RESET & AMUTE
6. Charging circuit
IP9001 has a charging circuit and it is independent from any other circuit.
Its power supply pin is CHGVCC which is directly connected to adapter.
Battery charging current is controlled by changing RCHG (between RCHG(pin33) and GND).
It also has an independent TSD circuit which has shut down temperature of 175OC and the hysteresis
temperature is 25OC
