General Description
of External Parts C1 (C1) Feedback capacitors Related to low roll-off frequency fL for
3dB (100µF, fL=60Hz).
A capacitance value of 47µF to 100µF is recommended.
Increasing the capacitance value makes the starting time (ts) later.
Key Features
- Low idling current (20mA/2 channels) enabling prolonged battery life.
- Less dependence of idling current on VCC.
- High power (5.3W typ. ×2).
- High ripple rejection (60dB at steady state). Since filters are arranged in 3 stages (including 1 stage inside the IC) to attain satisfactory ripple rejection at transient state, ripple occuring at the time of motor start can be prevented from mixing in.
- Low pop noise at the time of power supply ON/OFF and goo.
