PRODUCTION DATA
Table 9-3 provides example requirements for a single- or dual-coil relay application. Current regulation may also be configured to ensure the relay current is within the relay specification. This is important if the VM supply voltage is higher than the voltage rating of the relay.
DESIGN PARAMETER | REFERENCE | EXAMPLE VALUE |
---|---|---|
Motor supply voltage | VM | 12 V |
Microcontroller supply voltage | VCC | 3.3 V |
Single coil relay current | IRelay | 500 mA pulse for 200 ms |
Dual coil relay current | IOUT1, IOUT2 | 100 mA pulse for 200 ms |
