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

The SGM48523C and SGM48524C are dual highspeed low-side gate drivers for power switches. They have 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 for example 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 devices have internal pull-up/pull-down resistors on the input pins to ensure low state on the driver output when the input is floating.

The dual inverting SGM48523C and the dual non-inverting SGM48524C are both available in Green SOIC-8, TDFN-3×3-8L and MSOP-8 (Exposed Pad) packages.
