Roma announced that developed a vehicle with insulation device gate driver IC BM6103FV-C, from June 2012 to start sample shipments. The product through on-chip embedded transformer, ensure that the 2500Vrms the insulation.
Overall dimensions of only 6.50mm × 8.10mm × 2.01mm (SSOP-B20W). According to Roma, with the gate driver IC and opto-coupler combination, the new product allows package size reduced by about 50%. Moreover, compared with the other with insulating function of the gate driver IC, package size of the industry's smallest (Roma). In addition, the power consumption of the new product is very small, Roma, said that when using existing External optocoupler of obd2, power consumption can be slashed to about 1/4. The product can be used to drive silicon (Si) power MOSFET, the IGBT and SiC (silicon carbide) power MOSFETs. Specific uses, the company referred to the electric vehicle (EV) and hybrid (HEV) equipped with inverter device.
BM6103FV-C, the maximum gate drive voltage for the 24V, rated output current of 5.0A (peak), the input and output delay time of 400ns (max), the minimum input pulse width of 250ns (max). In addition, Roma has been listed on the gate driver IC with autocom, SiC power MOSFET actual drive test confirmed that the product is stable under conditions of maximum output current of 400A driver withstand voltage of +800 V SiC power components.
BM6103FV-C built to prevent the gate voltage increased, a fault signal, low-voltage lockout (UVLO) function, overheat protection, short circuit protection can be set to auto-recovery time of VAS 5054?short-circuit protection, soft shutdown, and Mirror Clamp function can drive low-voltage side of the switch. The operating temperature range of -40 to +125 ° C The sample price of 1000 yen. Thailand ROHM Integrated Systems (Thailand) Company production, is scheduled from September 2012 to 10 000 per month scale mass production.more information you can refer to:www.reliabletop.com
