It contains one P-channel high-side MOSFET and one N-channel low-side MOSFET with an integrated control IC in one package. With the P-channel high-side switch, the need for a charge pump is eliminated, which minimizes EMI. Pins IN and /INH are logic-level inputs and control the half-bridge output. The diagnostic and current sense IS pin outputs a current that is proportional to the current flowing through the half-bridge MOSFETs. The IS pin output represents current for the P-channel or the Nchannel, depending on which is active. The part is protected against a short to battery or ground of the out pin, over-current, over-temperature, over-voltage, and under-voltage conditions.
