BLOCK DIAGRAM/PIN CONFIGURATION (Top View)
Notes1.
V
DD
and V
SS
output internally boosted voltages. Do not connect a load directly to these pins.
2.
It is recommended that capacitors having a breakdown voltage of 20 V or higher be used as C
1
through
C
5
. Inserting a bypass capacitor of 0.1 to 1
μ
F in between V
CC
and GND is also recommended.
3.
Be sure to connect all the GND pins. Especially, make sure that pin 31 is connected; otherwise, the
μ
PD4726 will not operate normally. Be sure to leave the NC pins (pins 5 and 7) open.
4.
The pull-up resistors for D
IN1
through D
IN4
and STBY and the pull-down resistor for EN are active resistors.
