Design Notes
1 : Maximum voltage, maximum current
A voltage greater than the supply voltage, 7 to 16V, specified in the Allowable Operating Conditions must not be
applied to pins 1 and 7. The maximum current is 0.8A (peak). The rush
current at the time of start must not exceed the peak current.
2 : Output transistor protection
A resistor (or for fuse resistor) must be connected to the
VCC line to provide protection against output short,
output pin-to-GND short.
3 : Wiring
The bypass capacitors connected across pins 1, 7 and GND must not have an impedance common to other lines,
The GND line must be separated from other circuits.
4 : Provision against oscillation
In applications where motors with brush are used, a capacitor may be connectd across both terminals to prevent
the spark-caused noise. This capacitor is connected across the output pins of the LB1648, which may cause
oscillation to occur. In this case, the capacitor value must be made as small as possible or a resistor must be
connected in series.
5 : External Zener diode
The current flowing out of the VZ pin varies with the load and its
maximum value is approximately 1.2mA.
If you use a Zener diode of soft clip type and need an accuracy in voltage, a
current required for the Zener diode must be supplied externally.
