The SGM48211 is a half-bridge MOSFET driver with 4A peak source and sink output current capability, which makes it possible to drive large power MOSFETs with minimized switching losses. The two channels of high-side and low-side are totally independent with 3ns (TYP) delay matching between the turn-on and turn-off of each other.
The maximum withstanding voltage of the input stage of SMG48211 is 20V. Due to the -10VDC voltage endurance capacity of its input stage, the driver has enhanced robustness and can be interfaced to pulse transformers directly without using rectifier diodes. With a wide input hysteresis, the device can receive analog or digital PWM signals with improved noise immunity.
A 120V rated bootstrap diode is integrated internally to save the external diode and reduce PCB dimension size.
Under-voltage lockout (UVLO) is integrated in both the high-side and the low-side drivers. The output of each channel is forced low if the corresponding driving voltage falls below the specified threshold.
The SGM48211 is available in Green SOIC-8, SOIC-8 (Exposed Pad) and TDFN-4×4-8AL packages.
