Application information

A typical application using L6235Q is shown in Figure 23. Typical component values for the

L6235Q to improve the high frequency filtering on the power supply and reduce high

EN input to ground sets the shutdown time when an overcurrent is detected (see

sense resistors should be non-inductive resistors 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 Section 2). It is recommended to keep power ground and

signal ground separated on the PCB.
