SLVSFY8B February 2020 – August 2021 DRV8210
PRODUCTION DATA
The DRV8210 can be configured to half-bridge mode by leaving the MODE pin floating. In this mode, the device outputs can be used as low-side or high-side drivers. This allows the device to drive various loads such as one or two motors unidirectionally (only in one direction), solenoids, valves, and relays. Figure 9-9 shows the device used as a low-side driver on OUT1 and high-side driver on OUT2. Both loads may also be driven from the high-side or from the low-side. By tying the INx pins together and OUTx pins together, as shown in Figure 9-10 and Figure 9-11, the device can drive a single load with half of the RDS(on). This can accommodate larger current requirements. This configuration is called "parallel half-bridge mode."
In half-bridge mode, the other FETs and body diodes in the half-bridge will recirculate freewheeling current during the off-time of the PWM duty cycle, so extra external diodes are not needed.
