IR2114SSPBF - 600V Half-Bridge Gate Driver IC | Infineon
MPN: IR2114SSPBF ✓ Hoạt độngIR2114SSPBF Tóm tắt
A half-bridge gate driver is a power-management IC that translates low-power PWM control signals from a microcontroller or analog controller into the high-current drive required to switch the high-side and low-side FETs of a half-bridge power stage. It sits in the broader hierarchy of gate drivers -> power management ICs -> semiconductors, enabling efficient high-frequency switching of the power train while providing level shifting, bootstrap supply generation, and short-circuit protection for the power switches it controls.
Key features of the IR2114SSPBF include integrated over-current shutdown with a programmable fault-clear time, under-voltage lockout for both the floating (VBS) and low-side (VCC) supplies, dedicated shutdown input, matched propagation delay between the high-side and low-side channels, and a 2 A source / 3 A sink gate-drive current rating. The on-chip bootstrap diode eliminates the need for an external bootstrap rectifier in many low-to-medium-power designs, simplifying PCB layout and reducing BOM cost.
The IR2114SSPBF uses a level-shifted high-side channel that can swing up to 600 V referenced to the switch-node (VS), allowing direct drive of the high-side IGBT or MOSFET in a half-bridge. The shutdown logic and FAULT output combine to give the host controller a deterministic response to desaturation or over-current events, while the 50 ns typical propagation delay supports switching frequencies well above 100 kHz in hard-switched topologies.
Typical applications for the IR2114SSPBF include three-phase variable-frequency drives (VFDs), single-phase PFC front ends, welding inverters, uninterruptible power supplies (UPS), solar micro-inverters, and general-purpose half-bridge or full-bridge converters where the bus voltage stays below 600 V. The same part is widely used as a building block in motor-control kits and reference designs from Infineon's iMotion product line.
When designing with the IR2114SSPBF, the bootstrap capacitor must be sized to supply the gate-charge requirement of the high-side switch plus quiescent current over the worst-case on-time, and the VCC/VBS bypass network must use low-ESR ceramic capacitors placed as close to the IC as possible. Designers should also observe the maximum VS transient rating (self-clamped to VBS plus a diode drop) and provide adequate PCB creepage between the high-side floating supply and the low-voltage logic pins on the 24-SSOP footprint.

Ứng dụng tiêu biểu
IR2114SSPBF phù hợp cho 6 Áp dụngs: Three-Phase Variable-Frequency Drive (VFD), Solar Micro-Inverter Half-Bridge Stage, Uninterruptible Power Supply (UPS) PFC + Inverter, Induction Heating Inverter, Welding Inverter Power Stage, EV Charging Station Auxiliary Converter.
Three-Phase Variable-Frequency Drive (VFD)
The IR2114SSPBF drives each half-bridge in a 3-phase IGBT inverter for AC motor drives with DC bus voltages up to 600 V. Its 2 A source and 3 A sink gate-drive current switch 600 V/50 A IGBT modules in under 100 ns, while the integrated over-current shutdown protects the IGBTs against shoot-through and short-circuit faults. The 50 ns propagation delay keeps dead-time short, maximizing inverter efficiency in industrial VFD designs.

Solar Micro-Inverter Half-Bridge Stage
In a single-phase solar micro-inverter, the IR2114SSPBF drives the 600 V IGBT half-bridge that feeds the high-frequency transformer primary. The integrated bootstrap diode eliminates the external rectifier, reducing BOM cost and PCB area on the densely packed inverter board. The over-current comparator reacts in microseconds to grid-side faults, and the 600 V offset rating tolerates the 400-450 V DC bus of a typical residential PV micro-inverter.
Được đề xuất
Uninterruptible Power Supply (UPS) PFC + Inverter
The IR2114SSPBF is used both in the PFC front-end and the inverter stage of a double-conversion UPS rated up to 600 V DC bus. The under-voltage lockout (UVLO) on VCC and VBS prevents the IGBTs from operating in the linear region during power-up, while the dedicated shutdown pin allows the host DSP to latch the converter off in an over-current event. The 24-SSOP footprint fits easily on the UPS power board alongside the IGBT modules.
Được đề xuất
Induction Heating Inverter
A resonant half-bridge induction-heating inverter operates at 20-100 kHz and demands fast, high-current gate drive to minimize switching loss. The IR2114SSPBF delivers 2 A source and 3 A sink to switch 600 V/40 A IGBTs in under 80 ns, while the integrated over-current protection reacts to tank-detuning faults within one switching cycle. The 24-SSOP package dissipates the gate-drive loss comfortably with a small copper-pour heatsink.
Được đề xuất
Welding Inverter Power Stage
In an arc-welding inverter, the IR2114SSPBF drives the primary-side IGBT half-bridge of the high-frequency transformer that steps the rectified mains down to welding current levels. The 600 V offset rating handles the 540 V DC bus of a 3-phase rectified industrial mains, and the 3 A sink current reliably turns off the IGBTs even with high Miller-effect dv/dt. The shutdown pin interfaces directly with the welding current-sense comparator for fast arc-strike protection.
Được đề xuất
EV Charging Station Auxiliary Converter
In a Level-2 EV charging station, the IR2114SSPBF drives the half-bridge of an isolated auxiliary converter that generates 12 V battery and housekeeping rails. The 600 V rating isolates the auxiliary converter from the PFC boost-switch transients, while the integrated over-current comparator protects against output short circuits on the 12 V rail. The 24-SSOP package is robust enough for the elevated ambient temperatures inside a sealed charging-station enclosure.

Ghi chú thiết kế
Estimated: At a switching frequency of 50 kHz with a 100 nC total gate-charge IGBT (Q g = 100 nC) on each side of the half-bridge, the gate-drive loss for one IR2114SSPBF is approximately P_g = 2 * Qg * VCC * f_sw = 2 * 100 nC * 15 V * 50 kHz = 150 mW. The bootstrap supply adds another 1-3 mW of quiescent loss. Provide at least 1 square inch of copper pour under the exposed pad of the 24-SSOP to keep junction temperature rise below 20 C at this power level.
The 24-SSOP package has a thermal resistance theta_JA of approximately 80 C/W on a standard 1 oz 4-layer JEDEC board. At 150 mW gate-drive loss, junction temperature rises about 12 C above ambient. In high-temperature industrial enclosures (>70 C ambient), reduce switching frequency or use an external gate-drive buffer (e.g., 1EDI20N12AFXUMA1) to stay below the 150 C junction limit.
Place the VCC bypass capacitor (1 uF ceramic, X7R) within 3 mm of the VCC pin and the COM pin, with a short, wide trace to the gate-drive return. The bootstrap capacitor (typically 100 nF to 1 uF X7R, sized for Q_g of the high-side IGBT plus 30% margin) must be placed as close to the VBS pin as possible. Use a separate analog ground island for CS, FAULT, and logic pins to avoid switching-noise injection into the current-sense comparator.
Do not exceed the absolute maximum VS transient rating (typically -5 V to +VBS + 0.3 V). In hard-switched half-bridges, the VS pin can swing below COM due to stray inductance; add a 1-10 ohm gate resistor in series with the gate to damp the resulting ringing. The SD (shutdown) pin is internally pulled up - tie it to VDD if unused to avoid false shutdowns. Do not leave the FLT-CLR pin floating; a 100 kohm resistor to VDD sets a 10 us fault-clear time.
Separate the high-voltage switching loop (VS-HO-VBS) from the low-voltage logic loop (HIN/LIN-COM) by at least 5 mm of creepage on the PCB. Use a gate-drive return trace that runs parallel to and beneath the HO/LO gate traces to minimize loop inductance. Avoid routing the CS (current-sense) trace under the HO/LO traces or near the VBS bootstrap capacitor, as the dv/dt coupling can inject false faults into the over-current comparator.
