MOSFET H-bridge from Diodes Incorporated Reduces Footprint by 50%

PLANO, Texas — (BUSINESS WIRE) — January 21, 2015 — Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic and analog semiconductor markets, today announced two new H-bridge devices: the DMHC4035LSD and the DMHC3025LSD. This pair of MOSFET H-bridges simplifies motor driving and inductive wireless charging circuits by cutting component count and reducing PCB footprint by 50%. The 40V-rated H-bridge, the DMHC4035LSD, is targeted at meeting the requirements of automotive motor driving applications, whereas the 30V-rated H-bridge, the DMHC3025LSD, is suitable for 12V single-phase fan applications.

By packaging dual N-channel and dual P-channel MOSFETs to make a full H-bridge in just a single 5mm x 6mm SO-8 footprint, the DMHC3025LSD and DMHC4035LSD replace the equivalent four SOT23 or two SO-8 packages for a wide range of space-constrained automotive and industrial applications, including: low-power DC brushless motor driving, fan control and similar requirements for driving inductive loads.

The H-bridges’ space-saving advantage is complemented by the low RDS(ON) performance of the MOSFETs: typically 45mΩ at 10V VGS and 65mΩ at -10V VGS, respectively, for the 40V N-channel and P-channel devices. The minimal conduction losses resulting from the low on resistance mean the H-bridges are able to tolerate higher continuous current under motor stall conditions. Under +70ºC high ambient operating temperature, the 30V and 40V H-bridges can support continuous currents of 3A and 2A, respectively, thereby accommodating worst-case motor stall currents.
