Product details

Overview

IR7106STRPBF from Infineon Technologies (formerly International Rectifier) is a 700V high- and low-side gate driver IC for IGBTs and N-channel MOSFETs, featuring independent HO/LO outputs, 220ns/200ns typical propagation delays, 200mA/350mA peak output drive current, and 3.3V–15V logic-compatible inputs. It is designed for bootstrap-fed three-phase inverter stages in motor drives.

For engineers reviewing the IR7106STRPBF datasheet, IR7106STRPBF pinout, IR7106STRPBF application, or IR7106STRPBF equivalent, key selection criteria include V_OFFSET ≤ 700V, matched t_ON/t_OFF, UVLO thresholds on V_CC and V_BS, negative transient tolerance, and SOIC-8 package compatibility with high-voltage layout constraints.

Technical Context

The IR7106STRPBF integrates two independent gate drivers-high-side floating channel referenced to VS and low-side channel referenced to COM-each with level-shifted input logic and latch-immune HVIC architecture. Propagation delay matching (≤50ns max difference) enables precise dead-time control in high-frequency inverters up to 100 kHz.

It employs internal undervoltage lockout (UVLO) on both V_CC (8.2V threshold, 0.7V hysteresis) and V_BS (8.2V threshold, 0.7V hysteresis), ensuring safe turn-off during supply sag. The floating channel supports VS offset from –5V to +700V while maintaining logic integrity via pulse-filtered input stage.

Key Specifications

Parameter	Value and Actual Design Meaning
V_OFFSET	≤ 700V - Enables direct high-side switching in 600V-class DC bus systems without external level-shifting circuitry
t_ON/t_OFF	220ns / 200ns typ. - Supports PWM frequencies ≥500 kHz with minimal timing skew between channels
I_O+/I_O−	200mA / 350mA typ. - Drives gate charge Q_g ≤ 40nC at 15V V_GS within 100ns rise/fall targets
V_IN Logic Range	3.3V–15V compatible - Interfaces directly with MCU GPIO, FPGA I/O, or isolated digital controllers without level translation
UVLO Thresholds	V_CC: 8.2V±0.8V, V_BS: 8.2V±0.8V - Prevents partial turn-on during brown-out conditions in bootstrap circuits
Operating Temp	–40°C to +125°C - Qualified for industrial motor control enclosures and outdoor microinverter environments

Pinout & Package

IR7106STRPBF is housed in an 8-lead SOIC (SO8N) package with standard 1.27mm pitch, gull-wing leads, and creepage/clearance optimized for ≥700V working voltage. Pin 1 is V_CC, pin 4 is COM, pin 5 is V_B, pin 6 is H_O, pin 7 is V_S, and pin 8 is L_O.

Pin/Terminal	Circuit Role	Design Meaning
V_CC	Low-side supply and logic reference	Provides power and ground reference for LIN, COM, and LO; must be decoupled locally to suppress switching noise
HIN	High-side logic input	CMOS/LSTTL-compatible signal controlling HO; internally filtered to reject dV/dt-induced false triggering
LIN	Low-side logic input	Directly drives LO; shares same logic threshold as HIN but referenced to COM
COM	Low-side return path	Common ground for V_CC, LIN, and LO; must be low-inductance connection to power ground plane
V_B	Floating high-side supply rail	Bootstrap-supplied voltage feeding HO driver stage; requires external capacitor ≥0.1µF near pin
H_O	High-side gate output	Drives gate of high-side N-MOSFET/IGBT; referenced to V_S, not COM
V_S	Floating high-side return	Switching node connection for bootstrap capacitor; tolerates –5V to +700V transients relative to COM
L_O	Low-side gate output	Drives gate of low-side N-MOSFET/IGBT; referenced to COM; capable of 350mA sink current

Key Features

Feature	Design Value
Matched propagation delays	≤50ns t_ON/t_OFF mismatch ensures symmetrical dead-time insertion across phases in 3-phase inverters
Dual independent UVLO	Separate 8.2V thresholds on V_CC and V_BS prevent unsafe operation when either supply dips below gate drive minimum
Negative transient tolerance	Withstands –5V on V_S relative to COM - critical for inductive load commutation and shoot-through prevention
Bootstrap-ready architecture	No external level shifter required; integrated floating channel and pulse generator enable cost-effective half-bridge gate drive
Rugged HVIC process	Monolithic construction with latch-immune CMOS withstands >50V/ns dV/dt on V_S without false triggering

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRS21844SPBF	Lower V_OFFSET (600V), slower t_ON/t_OFF (320ns/240ns), no negative VS tolerance	Restricted to 400V DC bus systems; unsuitable for microinverter topologies requiring –5V transient margin	Select only if system V_DC ≤ 550V and thermal budget allows higher propagation delay
UCC27211D	Single-channel, non-isolated, no floating channel; 120V V_DD max; no UVLO on bootstrap rail	Requires external level shifter and separate bootstrap monitoring; not suitable for direct high-side bootstrap use	Use only in low-side-only or opto-coupled high-side configurations where isolation is externally managed

Compared with IRS21844SPBF and UCC27211D, IR7106STRPBF uniquely delivers 700V offset capability, matched sub-250ns delays, and integrated dual-rail UVLO-making it the only option qualified for compact, bootstrap-fed microinverters and high-reliability appliance drives.

FAQ

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

The IR7106STRPBF is rated for up to 50 V/ns dV/dt on the VS pin relative to COM, verified under standard test conditions. This rating ensures reliable operation during fast-switching transitions in 600V-class inverters without false triggering, provided PCB layout minimizes parasitic inductance in the VS return path.

Can IR7106STRPBF drive SiC MOSFETs?

Yes, IR7106STRPBF can drive discrete SiC MOSFETs with gate thresholds ≤4V and total gate charge ≤35nC at 15V V_GS, given its 200mA/350mA peak output and 220ns/200ns propagation delays. However, external negative gate bias or Miller clamp may be needed for full short-circuit robustness in hard-switched SiC applications.

Is a bootstrap diode required with IR7106STRPBF?

Yes-a fast recovery or Schottky bootstrap diode (e.g., 1N4148 or BAT54) is required between V_CC and V_B to charge the floating supply capacitor during low-side conduction. The diode must support ≥200mA peak forward current and reverse voltage ≥25V to ensure reliable V_BS regulation.

Does IR7106STRPBF include built-in shoot-through protection?

No, IR7106STRPBF does not integrate hardware shoot-through protection. It relies on external dead-time insertion in the controller (MCU/FPGA) or gate driver logic. Its matched propagation delays and clean logic filtering reduce timing uncertainty, but complementary HIN/LIN signals must be externally coordinated to avoid simultaneous high-side/low-side conduction.
