The NCV7518/NCV7518A Programmable Six-Channel Low-Side MOSFET Pre-Driver is part of the FLEXMOS automotive grade product family for driving logic level MOSFETs. The product can be controlled through a combination of serial SPI and parallel inputs. The device offers 3.3-V/5-V compatible inputs, and the serial output driver can be powered from either 3.3-V or 5-V. An internal power-on reset provides controlled power-up. A reset input allows external reinitialization, while an enable input allows simultaneous disabling of all outputs and diagnostics. Each channel independently monitors the drain voltage of its external MOSFET for fault conditions. The shorted load fault detection threshold is fully programmable using a combination of an externally programmed reference voltage and a discrete internal ratio. These ratios are SPI selectable, allowing different detection thresholds to be set for each channel. The fault-recovery operation of each channel is programmable and can be selected for latching shutdown or automatic retry. The status information for each channel is 3 bits coded for the fault type, provided via SPI communication. The FLEXMOS family offers application scalability through selection of external MOSFETs.

The FAN3223-25 ​​series of dual 4-A gate drivers provides high peak current pulses with short switching intervals for driving N-channel enhancement mode MOSFETs in low-side switching applications. The driver offers TTL or CMOS input thresholds. Internal circuitry holds the output low until the supply voltage is within operating range, providing undervoltage lockout. In addition, these drivers feature matched internal propagation delays between the A and B channels, making them suitable for applications requiring tightly clocked dual gate drivers, such as synchronous rectifiers. This also enables the parallel connection of the two drivers, effectively doubling the current capability to drive one MOSFET. The FAN322X driver integrates the MillerDrive structure for the final output stage. This bipolar MOSFET combination provides high current during the Miller plateau phase of the MOSFET turn-on/turn-off process to minimize switching losses while providing rail-to-rail voltage swing and reverse current capability. The FAN3223 provides two back drivers and the FAN3224 provides two non-back drivers. Each device has dual independent enable pins that default to an on state if left unconnected. In the FAN3225, each channel has two inputs of opposite polarity and can be configured as non-inverting or inverting with selectable enable using the second input. If one or both inputs are left unconnected, internal resistors bias the inputs so that the output pulls low to keep the power MOSFETs off.
