Product details

Overview

IR21014 from Infineon Technologies is a high-voltage, high-speed dual-channel gate driver IC for N-channel MOSFETs and IGBTs, featuring independent high-side (HO) and low-side (LO) outputs with 600 V offset capability, 130 mA/270 mA peak output current, 160 ns/150 ns typical propagation delay, and 5 V Schmitt-triggered logic inputs. It enables half-bridge topologies in motor drives and inverters.

For engineers reviewing the IR21014 datasheet, IR21014 pinout, IR21014 application, or IR21014 equivalent, key selection criteria include bootstrap-compatible floating channel operation up to +600 V, matched propagation delays (<50 ns), undervoltage lockout thresholds (8.2–9.8 V on VCC), and SOIC-14 package compatibility with industrial power stage designs.

Technical Context

The IR21014 integrates a high-voltage level shifter and latch-immune CMOS logic to drive high-side N-channel devices referenced to a floating VS node. Its HVIC process supports dV/dt immunity up to 50 V/ns and sustained VS offset of −5 V to +600 V while maintaining logic state integrity.

Both channels operate with in-phase input-to-output polarity (HIN→HO, LIN→LO), unlike the IR21024's out-of-phase configuration. The internal UV detection circuit monitors VCC only, with hysteresis of ~0.8 V between turn-on and turn-off thresholds.

Key Specifications

Parameter	Value and Actual Design Meaning
VOFFSET max	600 V - supports high-side switching in 400 V DC bus systems like solar inverters
IO+ / IO−	130 mA / 270 mA - sufficient to charge/discharge 1 nF gate capacitance in <100 ns
ton / toff (typ.)	160 ns / 150 ns - enables >3 MHz PWM operation with minimal dead-time uncertainty
Delay matching	≤50 ns - ensures symmetrical timing across HO/LO for precise half-bridge control
VCC range	10–20 V - compatible with standard 12 V or 15 V gate drive rails
Input logic	5 V Schmitt-trigger - rejects noise on HIN/LIN lines in electrically noisy motor control environments
VCC UV threshold	8.2 V (falling), 8.9 V (rising) - prevents erratic switching during brown-out conditions

Pinout & Package

IR21014 is housed in a 14-lead SOIC (narrow body) package with creepage and clearance suitable for reinforced insulation in industrial 600 V systems.

Pin/Terminal	Circuit Role	Design Meaning
1 (VCC)	Low-side and logic supply rail	Provides power to internal logic and LO driver; must be decoupled near pin
2 (HIN)	High-side logic input	In-phase control signal for HO; 5 V tolerant with Schmitt trigger for noise immunity
3 (LIN)	Low-side logic input	In-phase control signal for LO; identical electrical specs to HIN
4 (COM)	Low-side reference return	Ground reference for VCC, LIN, and LO; must connect to system power ground
5 (LO)	Low-side gate drive output	Drives N-MOSFET/IGBT source-connected to COM; rated 270 mA sink
6 (VB)	High-side floating supply	Bootstrap capacitor connection point; supplies HO driver stage referenced to VS
7 (HO)	High-side gate drive output	Drives N-MOSFET/IGBT source-connected to VS; rated 130 mA source
8 (VS)	High-side floating return	Reference node for VB and HO; swings from −5 V to +600 V relative to COM

Key Features

Feature	Design Value
Floating channel architecture	Enables high-side drive without isolated supplies via bootstrap, reducing BOM cost and board area
dV/dt immune level shifting	Withstands 50 V/ns transients on VS node-critical for fast-switching SiC/GaN half-bridges
Matched propagation delays	≤50 ns difference between HO and LO paths minimizes shoot-through risk in synchronous rectification
Independent UVLO on VCC	Prevents partial drive activation during power-up/down, avoiding MOSFET linear-mode stress
CMOS/LSTTL-compatible inputs	Direct interface with microcontrollers, FPGAs, or PWM controllers without level-shifting circuitry

Applications

Solar Inverters

Use Scenario: Three-phase BLDC or PMSM drives using six-pack IGBT/MOSFET modules.

IC Role / Device Role / Timing Role: Dual-channel gate driver providing synchronized, high-voltage isolated switching for upper/lower leg pairs.

Use Value: 160/150 ns propagation delays and ≤50 ns matching reduce dead-time uncertainty, improving torque ripple and efficiency.

Use Scenario: DC–AC conversion stage in string or microinverters interfacing PV panels to grid.

IC Role / Device Role / Timing Role: High-side/low-side driver for 600 V-class IGBTs in H-bridge or transformerless topologies.

Use Value: 600 V offset rating and dV/dt immunity ensure reliable operation under fast-rising PV string voltages and grid transients.

Industrial UPS

Induction Heating

Use Scenario: Online double-conversion UPS with bidirectional AC–DC and DC–AC stages.

IC Role / Device Role / Timing Role: Gate driver for IGBTs in active rectifier and inverter legs operating at 16–20 kHz.

Use Value: In-phase logic-to-output behavior simplifies control firmware versus out-of-phase alternatives like IR21024.

Use Scenario: Resonant half-bridge drivers in domestic or commercial induction cooktops.

IC Role / Device Role / Timing Role: High-frequency gate driver enabling ZVS operation at 20–100 kHz with minimal switching loss.

Use Value: 130 mA/270 mA peak output sustains fast gate charging for high-Q resonant tanks with large MOSFETs.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-side/low-side gate driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IR2104S	SOIC-8 package, no VS pin; integrated bootstrap diode; lower 500 V offset rating	Targeted at lower-voltage (<400 V) half-bridges where space is constrained	Select when board area is critical and 600 V margin is unnecessary
IRS21844PbF	SOIC-14, 600 V rating, but out-of-phase logic (HIN→HO inverted); higher 2.5 A peak output	Requires complementary PWM generation; suited for resonant LLC or synchronous buck converters	Choose when inverting logic is acceptable and higher drive strength is needed

Compared with IR2104S and IRS21844PbF, the IR21014 uniquely balances 600 V capability, in-phase logic, SOIC-14 pinout, and moderate drive strength-making it optimal for industrial motor drives requiring layout simplicity and voltage headroom.

FAQ

What is the maximum allowable dV/dt on the VS pin?

The IR21014 is rated for up to 50 V/ns on the VS node under recommended operating conditions. This dV/dt immunity is achieved through proprietary level-shifting circuitry and is validated per the datasheet test condition with VB = VS = 600 V. Exceeding this rate may cause false triggering or temporary loss of high-side output.

Can IR21014 drive SiC MOSFETs?

Yes-the IR21014 can drive SiC MOSFETs provided gate resistor values are selected to limit peak current within its 130 mA source / 270 mA sink capability and that the device's 600 V offset rating exceeds the application's maximum VS swing. Layout must minimize parasitic inductance on HO/VS paths to preserve dV/dt immunity.

Is there an internal bootstrap diode in IR21014?

No-the IR21014 does not integrate a bootstrap diode. An external fast-recovery diode (e.g., 1N4148 or equivalent) must be placed between VCC and VB to charge the bootstrap capacitor during low-side conduction. This differs from IR2104S, which includes an internal diode.

How does IR21014 handle negative VS excursions?

The IR21014 maintains logic functionality for VS down to −5 V relative to COM, as specified in the Recommended Operating Conditions. Below −5 V, the high-side driver is disabled, but the low-side channel (LO) remains fully operational since it references COM and VCC.
