Product details

Overview

IR2133S from Infineon Technologies is a high-voltage, high-speed 3-phase bridge driver IC with three independent half-bridge gate drive channels, rated for +600V floating offset operation, 200 mA/420 mA peak output current (HO/LO), 10–20 V gate supply range, and 750/700 ns typical turn-on/turn-off propagation delay. It integrates an analog current-sense amplifier and over-current shutdown for motor inverter applications.

For engineers reviewing the IR2133S datasheet, IR2133S pinout, IR2133S application, or IR2133S equivalent, key selection criteria include bootstrap-compatible high-side drive capability up to 600 V, matched propagation delays across all six outputs, integrated current sensing with blanking time, undervoltage lockout on both VCC and VB supplies, and fault reporting via open-drain FAULT output.

Technical Context

The IR2133S employs proprietary HVIC (High-Voltage IC) technology to integrate floating channel drivers capable of operating with VS referenced up to +600 V relative to COM. Its logic inputs accept 2.5 V–5 V CMOS/LSTTL signals, and outputs are out-of-phase with inputs-enabling direct PWM control without external inverters.

It features a dedicated current-sense amplifier (CA+, CA−, CAO) with 5–10 V/µs slew rate and ±30 mV input offset, plus programmable over-current trip via ITRIP pin with 400 ns blanking time. Shutdown (SD) and fault-clear (FLT-CLR) pins provide system-level protection coordination.

Key Specifications

Parameter	Value and Actual Design Meaning
VOFFSET max	+600 V - Enables high-side N-channel MOSFET/IGBT drive in 3-phase inverters up to 400 V AC line systems.
IO+ / IO−	200 mA / 420 mA - Sufficient peak current to charge/discharge 1 nF gate capacitance in <100 ns for typical 600 V power switches.
VOUT range	10–20 V - Supports standard gate drive voltage requirements for Si MOSFETs and IGBTs; transient tolerant to 25 V.
ton / toff (typ.)	750 / 700 ns - Enables >500 kHz PWM switching with minimal deadtime-induced distortion in servo drives.
Deadtime (typ.)	250 ns - Internally generated minimum interval prevents shoot-through during HS/LS transition in bridge legs.
ITRIP threshold	470–670 mV - Sets over-current trip level using external sense resistor; blanked for 400 ns to ignore switching noise.
UVLO thresholds	VCC & VB: 7.2–9.6 V (hysteresis 0.4 V) - Ensures stable gate drive only when supplies meet minimum regulation margin.

Pinout & Package

IR2133S is housed in a 28-lead SOIC (wide-body) package with creepage-optimized lead frame for high-voltage isolation. Pin assignments follow industry-standard 3-phase driver layout with grouped high-side (HIN/HO/VB/VS) and low-side (LIN/LO/VSS/COM) terminals.

Pin/Terminal	Circuit Role	Design Meaning
HIN1,2,3	Logic input for HO1,2,3	Inverted PWM input: high = HO low; enables direct connection to microcontroller GPIO without external inverters.
LIN1,2,3	Logic input for LO1,2,3	Non-inverted PWM input: high = LO high; supports complementary drive with HIN for half-bridge leg control.
HO1,2,3	High-side gate drive output	Floating output referenced to VSx; delivers 200 mA sink/source into gate load while sustaining +600 V offset.
LO1,2,3	Low-side gate drive output	Ground-referenced output delivering 420 mA sink current for fast turn-off of low-side switches.
VB1,2,3	Floating supply for high-side drivers	Bootstrap capacitor connection point; must be ≥10 V above VSx to ensure full gate drive swing.
VS1,2,3	Floating return for high-side drivers	Connects to phase-leg source/emitter node; withstands −5 V to +600 V transients with dV/dt immunity.
ITRIP	Over-current sense input	Accepts voltage from external shunt resistor; triggers shutdown when ≥470 mV (typ.) with 400 ns noise blanking.
FAULT	Open-drain fault indicator	Pulled low on UVLO or over-current; requires external pull-up; asserts within 650 ns of fault event.
FLT-CLR	Fault clear input	Negative-logic active-low signal; clears FAULT latch and resumes operation after fault condition is removed.
SD	Global shutdown input	Negative-logic enable: pulls all six outputs low and disables drivers until deasserted.
CA+, CA−, CAO	Current-sense amplifier I/O	Differential input (CA+/CA−) with rail-to-rail output (CAO); provides analog feedback for closed-loop current control.
VCC, VSS, COM	Fixed supply & grounds	VCC powers logic and low-side drivers (10–20 V); VSS = logic ground; COM = low-side power return (separate from VSS).

Key Features

Feature	Design Value
Floating channel architecture	Enables bootstrap-based high-side drive up to +600 V offset without external level shifters or isolated supplies.
Matched propagation delay	≤±50 ns variation across all six outputs ensures synchronized switching critical for low THD in motor sinusoidal commutation.
Integrated current-sense amplifier	Eliminates need for external op-amp; supports real-time phase current monitoring with 70 dB CMRR and 5–10 V/µs slew rate.
Programmable over-current shutdown	ITRIP pin accepts analog voltage from shunt; blanking time prevents false trips during switching transitions.
Independent UVLO per supply	Separate lockout on VCC and each VB supply prevents partial operation and ensures safe startup/shutdown sequencing.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 3-phase gate driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IR2135S	Higher VOFFSET rating (+600 V same), but VBS UVLO threshold raised to 9.2–11.6 V (vs. 7.2–9.6 V)	Better suited for systems with tighter VBS regulation margins; less tolerant of bootstrap droop under light load	Select IR2135S if VBS supply stability exceeds ±5% and system requires higher noise immunity on UVLO threshold
IRS2330JPbF	Monolithic 3-phase driver with integrated bootstrap diodes; no external VB decoupling required; 500 V rating	Reduces external component count but limits max bus voltage to 500 V; lacks analog current amplifier	Choose IRS2330JPbF for cost-sensitive, space-constrained designs where 500 V rating suffices and current feedback is handled externally

Compared with IR2135S and IRS2330JPbF, the IR2133S offers the broadest UVLO hysteresis (0.4 V), lowest VBS UVLO threshold (7.2 V), and unique integrated current-sense amplifier-making it optimal for variable-load motor drives requiring analog current loop closure and robust bootstrap operation down to marginal VBS conditions.

FAQ

What is the maximum allowable dV/dt on the VS pins of the IR2133S?

The IR2133S is specified for dV/dt immunity up to 50 V/ns on its VS1–VS3 pins, verified under test conditions with VB = 15 V and VS transient applied relative to COM. This rating ensures reliable operation during fast-switching events in hard-switched 3-phase bridges without false triggering of the high-side level shifter.

Can the IR2133S drive IGBTs directly without external gate resistors?

No-external gate resistors are required. While the IR2133S delivers 200 mA/420 mA peak output current, IGBT gate drive impedance must be tuned to control switching speed, minimize EMI, and prevent oscillation. Typical designs use 5–22 Ω series resistors on HO/LO outputs, selected based on IGBT Qg and desired dv/dt.

How does the ITRIP blanking time interact with PWM frequency in motor control?

The IR2133S applies a fixed 400 ns blanking window after each ITRIP assertion, independent of PWM frequency. At 20 kHz, this represents 0.8% of the period-sufficient to suppress turn-on spikes-but becomes negligible at higher frequencies. For FOC applications, blanking must be coordinated with software current sampling windows to avoid missing valid over-current events.

Is the CAO output buffered, and what load can it drive?

Yes-the CAO output is internally buffered with rail-to-rail capability and can source 7 mA or sink 1 mA. It drives standard ADC inputs directly (e.g., 10 kΩ || 10 pF), but for long traces or multiple loads, a unity-gain buffer is recommended to preserve bandwidth and common-mode rejection.
