Infineon Technologies IRSM515-084DA

Overview

IRSM515-084DA from Infineon Technologies (formerly International Rectifier) is a 250V, 3-phase integrated power module (IPM) for small-appliance motor drives, featuring 0.45Ω max R_DS(on) at 25°C, 1900V_RMS isolation, and DIP23A package. It integrates six Trench FREDFETs with matched high-voltage gate drivers, optimized dV/dt control, and 3.3V logic compatibility - deployed in energy-efficient fans and pumps.

For engineers reviewing the IRSM515-084DA datasheet, IRSM515-084DA pinout, IRSM515-084DA application, or IRSM515-084DA equivalent, key selection criteria include its 250V blocking voltage, 4.6A DC output per MOSFET, under-voltage lockout on all channels, open-source current sensing capability, and absence of integrated NTC thermistor (distinguishing it from IRSM505-084DA).

Technical Context

The IRSM515-084DA implements three independent half-bridge HVICs driving 250V Trench FREDFETs, each with matched propagation delay (0.7–1.5 µs turn-on, 0.9–1.5 µs turn-off) and built-in bootstrap functionality. Its driver architecture tolerates −V_S transients and supports 20 kHz PWM carrier frequency with 400 ns internal deadtime insertion.

Thermal design is enabled by 6.9°C/W junction-to-case resistance (high-side V-phase), while EMI performance is enhanced via optimized dV/dt slew rate control and low-inductance DIP23A packaging. The module operates across −40°C to +150°C case temperature range with 13.5–16.5 V V_CC supply and logic-compatible 0–5 V input voltage range.

FAQ

What is the maximum DC bus voltage supported by IRSM515-084DA?

The IRSM515-084DA supports a maximum DC bus voltage of 200 V under recommended operating conditions, with absolute maximum blocking voltage rated at 250 V. Operation above 200 V risks exceeding safe SOA limits during transients or overload, and is not validated per datasheet specifications.

Does IRSM515-084DA require external bootstrap capacitors?

No - the module integrates internal bootstrap diodes and supports external bootstrap capacitors only; no external bootstrap diodes are needed. A 0.22 µF ceramic capacitor per VB pin (VB1/VB2/VB3) to VSx is required for stable high-side gate drive operation.

How does IRSM515-084DA differ from IRSM505-084DA in thermal monitoring capability?

IRSM515-084DA has pin 11 (VTH) unconnected and contains no internal NTC thermistor, whereas IRSM505-084DA integrates a 47 kΩ ±5% NTC with B-constant 4050 K, providing analog temperature feedback referenced to COM for junction temperature estimation.

Can IRSM515-084DA be used with 3.3 V microcontrollers without level shifters?

Yes - its HIN/LIN inputs accept 0–5 V logic levels with 2.2 V typical positive-going threshold and 0.8 V negative-going threshold, fully compatible with 3.3 V CMOS outputs. No external level shifting is required, and input filtering ensures noise immunity in noisy motor environments.
