Infineon launches a 200 V half-bridge gate driver IC for a reliable start-up operation

The market for light electric vehicles (LEVs) such as e-bikes and e-scooters is cropping up with an increasing environmental awareness and the need to reduce CO2 and other emissions in urban areas. Engineers need the right semiconductor solutions and components to meet requirements such as reduced system size and cost, and fast time to market.

Infineon’s new 200 V half-bridge gate driver IC in a standard SOIC-8 (DSO-8) package helps designers to fulfil these requirements. The IRS2007S EiceDRIVER is a 200 V level-shift gate driver with undervoltage-lockout (UVLO) for V CC and V BS to provide higher reliability in start-up operations than previous products, claims the firm.

IRS2007S is tailored for low voltage (24 V, 36 V, and 48 V) and medium voltage (60 V, 80 V, 100 V, and 120 V) motor control applications in battery driven devices. They are typically found in power tools, household and garden equipment, as well as in light electric vehicles such as e-bikes and e-scooters, and in e-toys like drones.

The new IRS2007S includes integrated dead-time and shoot-through protection. It also features low quiescent currents, tolerance of negative transient voltage and dV/dt immunity. Therefore, the gate driver ensures the device reliability and reduces the BOM, according to Infineon.

Infineon noted that the chip utilizes Infineon’s advanced high-voltage IC technology to realize a compact, efficient and robust monolithic construction. A smaller MLPQ 4×4 14L (VQFN-14) package option is also available in the family.

The 200 V level-shift gate driver family comprises three-phase, half-bridge, and high and low side gate driver ICs, in both, Silicon-on-Insulator (SOI) and Junction Isolation (JI) options.

The three-phase gate driver ICs utilize Infineon’s SOI technology to provide functional isolation with industry-leading negative VS robustness and reduced level shift losses. Additionally, the SOI solution comes with integrated bootstrap diodes (BSD) to further reduce overall cost, simplify layout, and reduce PCB size.

Applications

  • Light electric vehicles such as e-scooter, e-bike and e-toys
  • Battery operated power tools
  • Battery operated garden tools
