Dual 5A, High-Speed, Low-Side Gate Driver with Negative Input Voltage Capability
GENERAL DESCRIPTION

The SGM48524D is a dual high-speed low-side gate driver for power switches. It has rail-to-rail driving capability and can sink or source up to 5A peak current with capacitive loads. The propagation delays are very short and well matched between the two channels that make the device well suited for applications that need accurate dual gate driving such as synchronous rectifiers. The matched propagation delays also allow for paralleling the two channels when higher driving current is required (such as for paralleled switches). The input voltage thresholds are fixed, independent of supply voltage (VDD), and compatible with low voltage TTL and CMOS logic. Noise immunity is excellent due to the wide hysteresis window between the input low and high thresholds. The device has internal pull-up/pull-down resistors on the input pins to ensure low state on the driver output when the input is floating.

The SGM48524D is available in Green SOIC-8, TDFN-3×3-8L and MSOP-8 (Exposed Pad) packages.
