... DETAILED OPERATING DESCRIPTION General The NCV7708A Double Hex Driver provides drive capability for 3 independent H−Bridge configurations High Side configurations with 6 Low Side configurations, or any combination of arrangements. Each output drive is characterized for a 500 mA load and has a typical 1.0 A surge capability (at 12 V). Strict adherence to integrated circuit die temperature is necessary. Maximum die temperature is 150° ...

... Bringing the CSB pin from condition immediately displays the information on the output data bit 0, thermal warning, even in the absence of a SCLK signal. As the temperature of the NCV7708A changes from a condition from below the thermal warning threshold to above the thermal warning threshold, the state of the SO pin changes and this level is available immediately when the CSB goes to 0 ...

... Any combination of motors and high side drivers can be designed in. This allows for flexibility in many systems. H−Bridge Driver Configuration The NCV7708A has the flexibility of controlling each driver independently. When the device is set H−Bridge configuration, the software design has to take care of avoiding simultaneous activation of connected HS and LS transistors ...
