Product details

Overview

IRS2509SPBF from Infineon Technologies (formerly International Rectifier) is a 600V high-speed half-bridge gate driver IC designed to independently control N-channel MOSFETs or IGBTs in high-side and low-side configurations. It features matched 750 ns / 250 ns propagation delays, internal 530 ns dead-time, 120 mA/250 mA peak output drive, and 10–20 V gate supply range-used in HID electronic ballasts for lamp ignition and regulation.

For engineers reviewing the IRS2509SPBF datasheet, IRS2509SPBF pinout, IRS2509SPBF application, or IRS2509SPBF equivalent, key selection criteria include floating channel voltage tolerance (600 V max), logic-level compatibility (3.3 V/5 V/15 V), under-voltage lockout thresholds (8.2 V hysteresis), cross-conduction prevention, and SOIC-8N package thermal limits (R_thJA = 200 °C/W).

Technical Context

The IRS2509SPBF integrates a high-voltage level-shifter and latch-immune CMOS logic to enable robust high-side operation up to 600 V offset with dV/dt immunity of 50 V/ns. Its dual-channel architecture provides independent IN-controlled outputs (HO in-phase with IN, LO inverted) plus dedicated SD shutdown input.

It implements fixed internal dead-time (530 ns typ.) between LO turn-off and HO turn-on, and between HO turn-off and LO turn-on, with ±60 ns matching tolerance. Propagation delay matching (MT ≤ 60 ns) ensures synchronous switching timing critical for resonant HID lamp control.

Key Specifications

Parameter	Value and Actual Design Meaning
Max V_OFFSET	600 V - supports high-side switch operation in 400 V AC line-referenced ballast topologies
t_ON/t_OFF (typ.)	750 ns / 250 ns - enables precise timing control for zero-voltage switching in resonant converters
Dead time	530 ns - prevents shoot-through during bridge transitions without external timing components
I_O+/I_O−	120 mA / 250 mA - sufficient gate charge delivery for 1–2 A IGBTs or 500 V/10 A MOSFETs
V_CC range	10–20 V - compatible with standard 12 V or 15 V isolated gate supplies
Logic input levels	3.3 V / 5 V / 15 V compatible - interfaces directly with microcontrollers, PWM controllers, or optocouplers
UVLO threshold	8.2 V (hysteresis 0.7 V) - ensures reliable startup and fault recovery in fluctuating supply conditions

Pinout & Package

IRS2509SPBF is housed in an 8-lead SOIC (SOIC-8N) package with creepage/clearance optimized for 600 V isolation. The package is RoHS-compliant, MSL2, and rated for industrial temperature range (–40 °C to +125 °C).

Pin/Terminal	Circuit Role	Design Meaning
IN	Logic input	Drives both HO (in-phase) and LO (inverted); TTL/CMOS-compatible, 3.3–15 V tolerant
SD	Shutdown input	Active-low; forces HO/LO into high-impedance state when pulled low; includes 5.2 V Zener clamp
VB	High-side floating supply	Connects to bootstrap capacitor; powers high-side driver stage referenced to VS
HO	High-side gate output	Sources/sinks current to drive N-channel MOSFET/IGBT gate; floats up to 600 V above COM
VS	High-side return	Reference node for VB and HO; swings with high-side switch source; withstands –50 V transient
VCC	Low-side and logic supply	Powers low-side driver and input logic; 10–20 V range with UVLO protection
LO	Low-side gate output	Drives low-side N-channel device referenced to COM; 250 mA sink capability
COM	Low-side ground reference	Common return for VCC, LO, and logic inputs; isolated from VS by HVIC level shifter

Key Features

Feature	Design Value
Matched propagation delay	≤60 ns difference between HO/LO t_ON and t_OFF - eliminates timing skew in symmetrical half-bridge operation
Integrated dead-time	530 ns fixed minimum - eliminates need for external dead-time circuitry in HID ballast designs
Negative transient tolerance	–50 V on VS (50 ns pulse) - sustains operation during inductive switching spikes in lamp ignition
Lower di/dt gate driver	Controlled rise/fall times (150 ns/50 ns typ.) - reduces EMI generation in high-frequency ballast circuits
Independent UVLO	Separate 8.2 V thresholds for VCC and VBS - prevents erratic switching during partial supply faults

Equivalent & Alternatives

The following parts are listed as comparable options for similar half-bridge gate driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRS2109SPBF	Lower quiescent current (IQ_CC = 1.5 mA typ.), improved noise immunity, same SOIC-8N package	Recommended for new designs per manufacturer; identical pinout and functional replacement	Select for new projects requiring extended lifecycle support and reduced standby power
FAN7382MX	Higher peak output (350 mA/650 mA), no internal dead-time, requires external timing network	Used in higher-current motor drives where programmable dead-time is preferred	Choose when greater drive strength or adjustable dead-time is required, accepting added external component count

Compared with IRS2509SPBF, IRS2109SPBF offers lower power consumption and updated qualification, while FAN7382MX trades integrated dead-time for higher drive capability and design flexibility-making IRS2109SPBF the direct upgrade path and FAN7382MX suitable for higher-power variants.

FAQ

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

The IRS2509SPBF is rated for 50 V/ns dV/dt on the VS pin under transient conditions. This specification ensures reliable operation during fast-switching events in resonant topologies, such as lamp ignition spikes in HID ballasts. The HVIC structure incorporates latch-immune design to prevent false triggering, and this rating is guaranteed by design-not just tested-per datasheet Note 2.

Does IRS2509SPBF support bootstrap and direct high-side supply configurations?

IRS2509SPBF supports only bootstrap-based high-side supply via VB and VS pins; it does not support direct high-side floating supply (e.g., isolated DC-DC). The VB pin must be connected to a bootstrap capacitor charged through a diode from VCC, and VS serves as the return for that supply. This configuration is validated for continuous operation up to 600 V offset and is standard in HID ballast implementations.

Can the internal dead-time be disabled or adjusted?

No-the 530 ns internal dead-time is fixed and non-adjustable. It activates automatically whenever external dead-time is shorter than the internal value; longer external dead-times remain unmodified. This architecture simplifies design for applications like HID ballasts where consistent, minimum dead-time is essential for shoot-through prevention and lamp stability.

Is IRS2509SPBF pin-compatible with IRS2109SPBF?

Yes-IRS2509SPBF and IRS2109SPBF share identical SOIC-8N pinout, logic interface behavior, and functional block diagram. The IRS2109SPBF replaces IRS2509SPBF in new designs with improvements including lower IQ_CC, enhanced ESD robustness, and updated industrial qualification, while maintaining full drop-in compatibility for existing layouts and firmware.
