Device Overview
Designed as a High-voltage Class-D MOSFET gate driver, Infineon Technologies IRS20957STRPBF uses the PG-DSO-16 package. Selection of this exact part is driven primarily by Device type (High-voltage Class-D MOSFET gate driver), Speaker channels (1), Power-stage voltage class (Up to +/-100 V).
Selection-Critical Data
| Parameter | Confirmed Data | Why It Matters |
|---|---|---|
| Device type | High-voltage Class-D MOSFET gate driver | Defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared. |
| Speaker channels | 1 | Defines the number or arrangement of parallel signal/control paths and therefore the resources a replacement must provide. |
| Power-stage voltage class | Up to ±100 V | Defines the electrical voltage envelope that must cover the intended operating or stress level. |
| Switching frequency | Up to 800 kHz | Defines the converter or clock switching rate and affects timing, passive-component selection, losses and EMI; it is not an RF operating band. |
| Exact Package | PG-DSO-16 | Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility. |
| Supply Voltage | Up to +/-100 V | Defines compatibility with the available board power rail and required bias range. |
Analog Selection Notes
For speaker channels, 1 is the approved value. Defines the number or arrangement of parallel signal/control paths and therefore the resources a replacement must provide.
At PG-DSO-16, the exact package determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility.
At High-voltage Class-D MOSFET gate driver, the device type defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared. For power-stage voltage class, Up to +/-100 V is the approved value. Defines the electrical voltage envelope that must cover the intended operating or stress level.
The switching frequency is Up to 800 kHz; this defines the operating frequency or RF band that must cover the intended signal frequencies. Supply Voltage is Up to +/-100 V. Defines compatibility with the available board power rail and required bias range.
