FAN7093 High-Current PN Half-Bridge Driver FAN7093 High-Current PN Half-Bridge Driver Description Features The FAN7093 is an integrated high-current half-bridge Path Resistance for a Full-Bridge Configuration: driver for electric motor drive applications. It contains Max. 30.5 m at 150C one P-channel high-side MOSFET and one N-channel 1 PWM Capability: > 60 kHz Combined w ith Active low -side MOSFET w ith an integrated control IC in one Free Wheeling package. With the P-channel high-side sw itch, the need for a charge pump is eliminated, w hich minimizes EMI. Sw itched-Mode Current Limitation for Reduced Pow er Dissipation In Over-Current Condition Pins IN and /INH are logic-level inputs and control the half-bridge output. The diagnostic and current sense IS Current Limit Protection: Typ. 43 A pin outputs a current that is proportional to the current Independent Current-Sense Output and Diagnostic flow ing through the half-bridge MOSFETs. The IS pin Flag for High and Low Sides output represents current for the P-channel or the N- channel, depending on w hich is active. Over-Temperature Protection (OTP) w ith Latch The part is protected against a short to battery or Shorted-Load Protection w ith Latch Behavior ground of the out pin, over-current, over-temperature, Over-Voltage Protection (OVP) w ith Lockout over-voltage, and under-voltage conditions. The FAN7093 provides a cost- and space-optimized solution Under-Voltage Protection (UVP) for protected high-current PWM motor drives.

Block Diagram The FAN7093 is a high-current half-bridge that contains conditions. In case of a short to VBATT or ground, the three separate chips in one package: one P-channel IS pin acts as an error flag. The error flag can be high-side MOSFET, one N-channel low -side MOSFET, detected as a logic HIGH level through an attached and w ith a control IC. All three chips are mounted on microcontroller. In an over-current situation, the control one common lead frame, using chip-on-chip and chip IC turns off the MOSFETs and tries to turn them back by-chip technologies. The pow er MOSFETs are vertical on after a cool dow n time of 140 s (typical). The control MOS transistors to ensure minimum on-state resistance. IC protects the MOSFETs against over-voltage, under voltage, and overtemperature conditions. The dead Using a P-channel high-side sw itch eliminates a charge time, to prevent shoot-through betw een the P- and N- pump and reduces EMI. A microcontroller is able to channel MOSFET, is also generated by the control IC. control the logic level inputs of IN and /INH of the half- The slew rate of the outputs can be adjusted through an bridge. The diagnostic pin IS is a current output stage external resistor connected to the SR pin. The FAN7093 that delivers a proportional current through the P- can be combined w ith another FAN7093 to form a full- channel and N-channel MOSFETS, depending on w hich bridge drive. Multiple FAN7093 can be combined in full- is being activated, w ith the IN or /INH pin forcing or half-bridge three-phase drive configurations. www.onsemi.com 2
