... NCV7703 Triple Half-Bridge Driver with SPI Control The NCV7703 is a fully protected Triple Half−Bridge Driver designed specifically for automotive and industrial motion control applications. The three half−bridge drivers have independent control. This allows for high side, low side, and H−Bridge control. H−Bridge control provides forward, reverse, brake, and high impedance states ...

... Table 1 defines the programming bits and diagnostic bits. Figure 11 displays the timing diagram associated with Table 1. Fault information is sequentially clocked out the SO pin of the NCV7703 as programming information is clocked Frame Detection Input word integrity (SI) is evaluated by the use of a frame consistency check. The word frame length is compared bit acceptable word length before the data is latched into the input register ...

... Hysteresis in the UVLO circuits results in glitch free operation during power up/down. H−Bridge Driver Configuration The NCV7703 has the flexibility of controlling each half bridge driver independently. This allows for high side, low side and H−bridge control. H−bridge control provides forward, reverse, brake and high impedance states. ...
