STMicroelectronics recommends a thermal pad on the bottom of the package, connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
Ensure proper heat sinking, keep the junction temperature (Tj) below 150°C, and follow the recommended operating conditions and derating curves in the datasheet.
The maximum allowed voltage on the gate driver output is 20V, as specified in the datasheet. Exceeding this voltage may damage the device.
Yes, the STPS2045CG can be used in a half-bridge configuration, but ensure proper dead-time management and synchronization between the high-side and low-side switches to prevent shoot-through currents.
The minimum input capacitance required for the bootstrap capacitor can be calculated using the formula: Cboot_min = (Ipeak x t_on) / (Vboot x ΔVboot), where Ipeak is the peak current, t_on is the on-time, Vboot is the bootstrap voltage, and ΔVboot is the allowed voltage droop.
