STMicroelectronics STIB1560DM2-Z

Overview

STIB1560DM2-Z from STMicroelectronics is a fully isolated 3-phase intelligent power module (IPM) integrating 15 A / 600 V N-channel superjunction MOSFETs with embedded gate drivers, undervoltage lockout, short-circuit protection, smart shutdown, and a built-in temperature sensor. It delivers 0.15 Ω typical R_DS(on), 1600 V_rms/min isolation, and operates up to 125 °C case temperature - deployed in compact air conditioner inverters and PMSM motor drives.

For engineers reviewing the STIB1560DM2-Z datasheet, STIB1560DM2-Z pinout, STIB1560DM2-Z application, or STIB1560DM2-Z equivalent, this page provides verified technical context, real-world design meaning for key specs, SDIP2B-26L package layout, fault timing behavior, thermal sensor output calibration, and validated alternatives for ACIM and BLDC inverter designs.

Technical Context

The STIB1560DM2-Z integrates two independent control ICs driving six high-voltage MOSFETs in a 3-phase bridge configuration, with separate high-side (V_BOOTU/V/W, HINU/HINV/HINW) and low-side (LINU/LINV/LINW, V_CCL) logic inputs compatible with 3.3 V/5 V TTL/CMOS. Its smart shutdown architecture triggers immediate gate disable (<24 µs OC response) via internal comparator feedback, bypassing external RC delay dependence.

It features integrated bootstrap diodes, fast soft-recovery diodes (V_SD = 0.98–1.36 V at 15 A), and a ratiometric TSO voltage output (0.974–1.345 V at 25 °C) proportional to junction temperature. Isolation is achieved through a reinforced SDIP2B-26L type Z1 package rated at 1600 V_rms/min per UL 1557.

FAQ

What is the maximum recommended PWM frequency for STIB1560DM2-Z?

The datasheet specifies 20 kHz as the maximum recommended PWM frequency under TC ≤ 100 °C. At this frequency, switching losses (E_ON + E_OFF ≈ 0.87 mJ total per switch event) remain within thermal limits when combined with 0.15 Ω conduction loss. Exceeding 20 kHz risks exceeding R_thJC = 1.1 °C/W derating at 15 A continuous load.

How does the smart shutdown function differ from conventional SD pin behavior?

Unlike standard shutdown pins that require external RC timing, STIB1560DM2-Z's smart shutdown activates gate disable immediately upon comparator trigger (<24 µs), while simultaneously asserting the SD open-drain output. The external RC network only affects restart timing - not fault response latency - enabling robust protection even with large filter capacitors.

Can TSO be used directly with a standard MCU ADC without signal conditioning?

Yes. TSO outputs 0.974–1.345 V over −40 to +125 °C, fully compatible with 3.3 V MCU ADCs having ≥10-bit resolution. No amplification or level-shifting is needed; a 1–10 nF decoupling capacitor near the MCU ADC input suffices for noise immunity per Section 6.1 guideline #5.

What is the purpose of separate NU, NV, NW pins instead of a single N terminal?

Separate negative DC terminals (NU/NV/NW) provide individual low-inductance return paths for each phase leg, minimizing crosstalk and ground bounce during high-di/dt switching. This layout prevents false triggering of the internal comparator and improves stability in high-EMI motor drive environments - confirmed in Figure 8 application circuit and guideline #11.
