Notes
1. To guarantee a powerless brake duration of at least 10 s. A low leakage capacitor must be used (<0.1 µA).
2. For a frequency range of 25 to 100 kHz. CSTOSC = 0.775 (Iref/fPWM).
3. For a RESETA/RESETP pulse duration of approximately 100 ms.
CHARACTERISTICS
VDD = 12 V; VDDA = VDDD = 5 V; Tamb = 25 °C; unless otherwise specified.
