Product details

Overview

IR2102 from Infineon Technologies is a high-voltage, high-speed dual-channel gate driver IC designed for driving N-channel MOSFETs and IGBTs in half-bridge configurations. It features independent high-side (HO) and low-side (LO) outputs with out-of-phase logic inputs, 600 V offset voltage tolerance, 160 ns / 150 ns typical turn-on/turn-off propagation delays, and 10–20 V gate drive supply range. It is used in motor control inverters and SMPS where bootstrap-based high-side switching up to 600 V is required.

For engineers reviewing the IR2102 datasheet, IR2102 pinout, IR2102 application, or IR2102 equivalent, key selection considerations include its out-of-phase input logic behavior (vs. IR2101), matched channel delay (≤50 ns), dV/dt immunity, undervoltage lockout thresholds (8.2–9.8 V rising, 7.4–9 V falling), and SOIC/PDIP package compatibility with industrial-level thermal performance.

Technical Context

The IR2102 implements a monolithic high-voltage IC (HVIC) architecture with integrated level-shifting and pulse filtering for robust high-side operation. Its floating channel uses bootstrap biasing referenced to VS, enabling gate drive of high-side N-MOSFETs operating up to +600 V relative to COM.

Logic inputs HIN and LIN are CMOS/LSTTL-compatible (3.3 V/5 V/15 V), with IR2102 configured for inverted output polarity: HO follows LIN and LO follows HIN. Undervoltage lockout (UVLO) independently monitors VCC (8.2–9.8 V trip) and VB (not specified in J-column data but confirmed via IRF PD60043 Rev.O), preventing erroneous output during supply brownout.

Key Specifications

Parameter	Value and Actual Design Meaning
VOFFSET	600 V max - supports high-side switching in 400 V AC line-connected inverters and PFC stages
IO+/IO−	130 mA / 270 mA - drives gate capacitance ≤2 nF at <100 ns rise/fall under load
ton/toff	160 ns / 150 ns typ. - enables >3 MHz PWM operation with minimal dead-time uncertainty
Delay Matching	≤50 ns - ensures precise timing alignment between HO and LO edges for reduced shoot-through risk
VCC Range	10–20 V - compatible with standard 12 V or 15 V gate driver rails; UVLO active below ~8.2 V
Logic Polarity	HIN→LO, LIN→HO (inverted) - simplifies control logic in synchronous rectification and 3-phase bridge topologies
dV/dt Immunity	50 V/ns - suppresses false triggering during fast high-side switching transients

Pinout & Package

IR2102 is available in 8-lead PDIP (IR2102) and 8-lead SOIC (IR2102S) packages, both with identical pin mapping and thermal characteristics (R_thJA = 125 °C/W for PDIP, 200 °C/W for SOIC).

Pin/Terminal	Circuit Role	Design Meaning
HIN	Logic input for low-side output (LO)	Inverted control: high HIN → LO high; enables direct PWM-to-LO mapping without external inversion
LIN	Logic input for high-side output (HO)	Inverted control: high LIN → HO high; allows single-controller drive of complementary half-bridge
HO	High-side gate drive output	Floating output referenced to VS; drives gate of high-side N-MOSFET in bootstrap configuration
LO	Low-side gate drive output	Ground-referenced output; drives gate of low-side N-MOSFET with 270 mA sink capability
VB	High-side floating supply	Bootstrap capacitor connection point; supplies HO stage when VS swings high
VS	High-side floating return	Reference node for HO and VB; tied to source of high-side MOSFET; withstands −5 V to +600 V
VCC	Low-side and logic supply	Powers internal logic, UVLO, and LO stage; regulated 10–20 V input required
COM	Low-side ground reference	Return path for LO, logic, and VCC; must be low-inductance connection to PCB ground plane

Key Features

Feature	Design Value
Out-of-phase logic inputs	HIN controls LO, LIN controls HO - eliminates need for external inverters in half-bridge PWM control
Matched propagation delay	≤50 ns difference between HO and LO turn-on/turn-off - reduces minimum dead-time requirement in motor drives
600 V offset capability	VS rated from −5 V to +600 V - supports universal input AC/DC converters and 3-phase inverter legs
3.3 V/5 V/15 V logic compatible	VIH/VIL thresholds scale with VCC - interfaces directly with MCU GPIO, FPGA I/O, or isolated digital controllers
Integrated UVLO on VCC	8.2 V (falling), 8.9 V (rising) - prevents partial turn-on of power devices during supply ramp-up or dip

Applications

Use Scenario: Active clamp forward converter with synchronous rectification in telecom power supply.

IC Role / Device Role / Timing Role: Drives high-side MOSFET in active clamp switch and low-side SR FET with precise edge alignment.

Use Value: dV/dt immunity (50 V/ns) prevents false triggering during clamp ringback; 130 mA/270 mA drive sustains 10 ns rise time into 1.5 nF gate load.

UPS Half-Bridge

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
IR2101	In-phase logic: HIN→HO, LIN→LO; otherwise identical specs and pinout	Requires external inverter or controller-level inversion for complementary half-bridge drive	Select IR2101 only when existing firmware or logic design assumes non-inverted input mapping
IRS21844	Higher drive current (260 mA/650 mA), integrated bootstrap diode, 600 V rating, same 8-pin SOIC	Better suited for higher gate charge loads (>2.5 nF) and space-constrained designs needing integrated diode	Choose IRS21844 when upgrading drive strength or eliminating discrete bootstrap diode without changing layout

Compared with IR2101, IR2102 saves one inverter gate per channel in half-bridge control; versus IRS21844, it offers lower cost and simpler BOM but requires external bootstrap diode and delivers less peak current-making it optimal for <2 nF gate loads and cost-sensitive industrial inverters.

FAQ

What is the logic polarity relationship between inputs and outputs on the IR2102?

The IR2102 uses inverted logic mapping: a logic-high signal on HIN drives LO high, and a logic-high signal on LIN drives HO high. This differs from the IR2101 (non-inverted). The functional block diagram and lead definitions in the official datasheet PD60043 Rev.O confirm this behavior, and it is implemented via internal pulse filters and latch-immune HVIC logic.

Can IR2102 drive both MOSFETs and IGBTs reliably?

Yes-IR2102 is explicitly characterized for both N-channel MOSFETs and IGBTs. Its 130 mA/270 mA peak output current, 10–20 V gate drive range, and 160 ns/150 ns propagation delays meet typical gate charge requirements for 30–100 A IGBT modules and 50–200 A MOSFETs used in industrial inverters. The datasheet specifies test conditions using both device types.

Does IR2102 include bootstrap diode integration?

No-the IR2102 does not integrate a bootstrap diode. External diode (e.g., 1N4148 or fast recovery type) and capacitor (typically 0.1–1 µF ceramic + 10 µF electrolytic) must be connected between VCC and VB. This is clearly shown in the typical connection diagram (Figure 1) and confirmed in Application Note AN-978, which details bootstrap design for IR210x drivers.

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

The absolute maximum dV/dt rating at the VS pin is 50 V/ns, as specified in the Absolute Maximum Ratings table of PD60043 Rev.O. This value is validated under worst-case conditions (VB = VS = 600 V) and ensures reliable operation without false triggering during fast high-side switching transitions in hard-switched topologies.
