DMHC3025LSD and DMHC4035LSD MOSFET H-Bridges

Diodes Incorporated has extended its family of dedicated MOSFET H-bridges with the DMHC3025LSD and DMHC4035LSD. These components are designed for space limited single-phase brush and brushless motor driving and inductive wireless charging circuits.

These 30 V and 40 V rated MOSFETs have low R_DS(ON) performance allowing them to operate under a high 70°C ambient temperature, while still supporting continuous currents of 3 A and 2 A respectively, thereby accommodating worst-case motor stall currents.

• Reduce footprint
  • Using single SO8 package, with 5 mm x 6 mm footprint, these H-bridges can save PCB space, reduce component count, and assembly costs
• Low R_DS(ON)
  • < 50 m and minimizes conduction losses, enabling the H-bridges to tolerate high-continuous-current under motor stall conditions
• High pulsed current
  • 30 A peak pulse capability allows for a high in-rush current to be drawn safely during the start-up of the inductive load
• Max Drain Voltage
  • 40 V and 30 V V_DSS provide sufficient headroom for the intended 24 V and 12 V V_CC rail voltages.

• DC motor control
• DC-AC inverters
