ROHM 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, and the thermal pad should be connected to a ground plane or a dedicated heat sink.
To ensure reliable operation at high temperatures, it's essential to follow the recommended derating curves for the device. Additionally, ensure good thermal design, use a heat sink if necessary, and avoid exceeding the maximum junction temperature (Tj) of 150°C.
The maximum allowed voltage on the input pins is 5.5V, which is the absolute maximum rating. However, for reliable operation, it's recommended to keep the input voltage within the recommended operating range of 3.3V to 5V.
ROHM recommends using ESD protection devices, such as TVS diodes or ESD arrays, on the input lines to protect the device from electrostatic discharge. Additionally, follow proper handling and storage procedures to prevent ESD damage.
ROHM recommends powering up the VCC pin first, followed by the input signals. This ensures that the internal circuitry is properly initialized and reduces the risk of latch-up or other malfunction.
