... The HIP6005 monitors the output voltage with a window comparator that tracks the DAC output and issues a Power Good signal when the output is within 10%. The HIP6005 protects against over-current conditions by inhibiting PWM operation. Built-in over-voltage protection triggers an external SCR to crowbar the input supply. The HIP6005 ...

... T Functional Description Initialization The HIP6005 automatically initializes upon receipt of power. Special sequencing of the input supplies is not necessary. The Power-On Reset (POR) function continually monitors the input supply voltages. The POR monitors the bias voltage at the VCC pin and the input voltage (V OCSET pin ...

... MOSFET power loss (see the equations below). These equations assume linear voltage- current transitions and are approximations. The gate- charge losses are dissipated by the HIP6005 and do not heat the MOSFET. However, large gate-charge increases the switching interval TRAN MOSFET switching losses ...

... F is the switching frequency. S Standard-gate MOSFETs are normally recommended for use with the HIP6005. However, logic-level gate MOSFETs can be used under special circumstances. The input voltage, upper gate drive level, and the MOSFETs absolute gate-to-source voltage rating determine whether logic-level MOSFETs are appropriate ...
