AVDD 23 PWR O 3.3-V internal regulator output. Connect a X5R or X7R, 2.2-µF (no load) or 4.7-µF (up to 20 mA load), 6.3-V ceramic capacitor between the AVDD1 and AGND pins. This regulator can source up to 20 mA externally. BRAKE 31 I High → Brake the motor Low → Normal motor operation If BRAKE pin is not used, connect to AGND directly. If BRAKE pin is used to brake the motor, use an external 100-kΩ pull-down resistor (to AGND). CP 6 PWR Charge pump output. Connect a X5R or X7R, 1-µF, 16-V ceramic capacitor between the CP and VM pins. CPH 5 PWR Charge pump switching node. Connect a X5R or X7R, 100-nF, ceramic capacitor between the CPH and CPL pins. TI recommends a capacitor voltage rating at least twice the normal operating voltage of the device. CPL 4 PWR DACOUT2/S OX 32 O Multipurpose pin: DAC output when configured as DACOUT2 CSA output configured as SOX DACOUT1 34 O DAC output DACOUT1 DACOUT2 33 O DAC output DACOUT2 DGND 2 GND Device digital ground. Refer Layout Guidelines for connections recommendation.
