Application information
A typical application using L6229Q is shown in
application are shown in
100 nF to 200 nF should be placed between the power pins VS
the L6229Q to improve the high frequency filtering on the power supply and reduce high
frequency transients generated by the switching. The capacitor (C
EN input to ground sets the shut down time when an over current is detected (see
overcurrent protection). The two current sensing inputs (SENSE
connected to the sensing resistor R
layout. The sense resistor should be non-inductive resistor to minimize the dI/dt transients
across the resistor. To increase noise immunity, unused logic pins are best connected to 5 V
(high logic level) or GND (low logic level) (see pin description). It is recommended to keep
power ground and signal ground separated on PCB.
