Product details

Overview

IR2136STR from Infineon Technologies is a high-voltage, high-speed 3-phase bridge driver IC with three independent half-bridge gate drivers for N-channel MOSFETs and IGBTs. It operates up to +600V VS offset, features matched 400ns/380ns turn-on/turn-off propagation delays, 3.3V logic compatibility, and integrated over-current shutdown with RCIN-programmable fault-clear delay. It is used in industrial motor inverters requiring robust bootstrap-based high-side drive.

For engineers reviewing the IR2136STR datasheet, IR2136STR pinout, IR2136STR application, or IR2136STR equivalent, key selection criteria include floating channel dV/dt immunity, UVLO thresholds (8.9V/8.2V), ITRIP threshold (0.46V), HO/LO phase relationship (inverted), and SOIC-28 package thermal resistance (78°C/W).

Technical Context

The IR2136STR integrates proprietary HVIC technology for monolithic high-side floating channel operation, enabling direct drive of high-side N-channel switches in 3-phase topologies without external level shifters. Its internal shoot-through prevention logic enforces deadtime between complementary HO/LO outputs per channel, and all six drivers share matched propagation delays (±40ns) to minimize timing skew in PWM-controlled inverters.

It implements dual-stage undervoltage lockout (UVLO) on both VCC and VBx supplies, with hysteresis (0.7V) to prevent oscillation during supply ramp-up. The FAULT pin is open-drain and latched only on over-current; recovery requires external RC network on RCIN to generate a 1.3–2ms clear pulse after ITRIP deassertion.

Key Specifications

Parameter	Value and Actual Design Meaning
V_BS Range	10–20V: sets minimum bootstrap capacitor voltage needed to sustain high-side gate drive under load
t_on/t_off	400ns/380ns typ.: enables ≤250kHz PWM switching with precise edge alignment across all 6 channels
V_ITRIP	0.46V typ.: allows low-value current-sense resistor (e.g., 5mΩ) for accurate phase-current trip detection
V_CC UVLO+	8.9V: prevents operation below safe logic and driver bias margin; hysteresis ensures clean restart
dV/dt Immunity	50 V/ns: suppresses false triggering during fast high-side switching transients in 600V bus systems
Logic Compatibility	3.3V CMOS/LSTTL: interfaces directly with modern microcontrollers and FPGA I/O without level-shifting
R_THJA	78°C/W (SOIC-28): defines maximum power dissipation (1.6W) at T_A = 25°C for thermal design

Pinout & Package

IR2136STR is supplied in a 28-pin SOIC package with exposed thermal pad (RoHS-compliant, Pb-free). Pin assignments are validated per Infineon PD60166 revS datasheet and confirmed on Digi-Key and Mouser product pages.

Pin/Terminal	Circuit Role	Design Meaning
VCC	Low-side & logic supply input	Provides 10–20V bias for internal logic, level shifters, and LO drivers; must be decoupled locally
VSS	Logic ground reference	Common return for HIN/LIN/EN/ITRIP inputs; isolated from COM and VS nodes
COM	Low-side power ground	Return path for LO1–LO3 outputs and current-sense amplifier; tied to system power ground
HIN1–HIN3	High-side PWM inputs	Inverted logic: high input disables HO output; compatible with 3.3V controllers
LIN1–LIN3	Low-side PWM inputs	Inverted logic: high input disables LO output; synchronized with HIN for deadtime control
HO1–HO3	High-side gate drivers	Floating outputs referenced to VS1–VS3; drive gates of high-side N-MOSFETs/IGBTs
LO1–LO3	Low-side gate drivers	Ground-referenced outputs; sink/source ≥200mA peak to charge/discharge gate capacitance
VS1–VS3	High-side floating source monitors	Provide return reference for HO outputs; withstand −5V to +600V relative to COM
VB1–VB3	Bootstrap supply inputs	Accept charged bootstrap capacitors; each floats with its respective VS node
ITRIP	Over-current sense input	Analog comparator input; 0.46V threshold triggers simultaneous shutdown of all six outputs
RCIN	Fault-clear timing input	RC network here sets automatic FAULT recovery delay (1.3–2ms); open-drain FAULT asserts low
EN	Global enable/disable	Active-low: pulls all HO/LO outputs low when asserted; overrides individual HIN/LIN states
FAULT	Open-drain fault indicator	Drives low on UVLO or over-current; high-impedance when cleared; requires external pull-up

Key Features

Feature	Design Value
Cross-conduction prevention logic	Hardware-enforced deadtime (220–360ns) eliminates shoot-through risk without firmware intervention
Matched propagation delay	≤70ns max mismatch across all 6 channels ensures synchronous switching critical for vector control
Externally programmable fault clear	RCIN pin accepts user-defined R-C network to set precise auto-recovery time (1.3–2ms)
−5V to +600V VS tolerance	Enables use in 400VAC and 560VDC bus applications with margin for transient overvoltage
Lower di/dt gate driver	Reduced slew rate improves noise immunity in EMI-heavy motor drive environments

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
IR21362STR	Higher V_CC UVLO+ (10.4V), in-phase HO outputs, 3.3V-compatible but higher VIH (2.7V)	Better suited for systems with tighter VCC regulation and where non-inverted HO simplifies control logic	Select when using 12V logic rails and requiring faster fault recovery (same t_on/t_off but lower ITRIP hysteresis)
IR21363STR	V_CC range 12–20V, UVLO+ 11.2V, same inverted HO, 0.46V ITRIP threshold	Optimized for 15V auxiliary supplies and higher bus voltage designs (>500V DC link)	Choose for improved noise margin in high-EMI industrial enclosures where 11.2V UVLO prevents spurious shutdown

FAQ

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

The IR2136STR is rated for 50 V/ns dV/dt on VS1–VS3 pins. This specification ensures reliable operation during fast high-side switching transitions in 600V bus systems without false triggering of internal level shifters. Exceeding this rate may cause erratic HO output behavior or premature UVLO activation due to coupling into the floating channel.

How does the RCIN pin control fault recovery timing?

The RCIN pin accepts an external resistor-capacitor network that sets the FAULT clear delay. With R = 2 MΩ and C = 1 nF, the typical clear time is 1.65 ms. The internal circuitry monitors RCIN voltage; once it exceeds 8 V (at VCC = 15 V), the FAULT pin returns to high-impedance, re-enabling all outputs after the programmed interval.

Can IR2136STR drive both MOSFETs and IGBTs?

Yes - the IR2136STR is explicitly qualified to drive both N-channel power MOSFETs and IGBTs. Its 200mA source/350mA sink peak output current, 125ns rise time, and 75ns fall time meet gate drive requirements for devices up to 50A/600V. The 3.3V logic interface and bootstrap architecture suit both device types in 3-phase bridge configurations.

What is the purpose of the EN pin, and how does it interact with HIN/LIN inputs?

The EN pin is an active-low global enable that overrides all HIN and LIN inputs. When pulled low, it forces all HO1–HO3 and LO1–LO3 outputs to low-impedance off-state regardless of HIN/LIN states. This provides hardware-level emergency shutdown independent of controller firmware, essential for safety-critical motor and UPS applications.
