Holt Integrated Circuits recommends a 4-layer PCB with a solid ground plane, and thermal vias under the device to dissipate heat. A minimum of 1 oz copper thickness is recommended for the top and bottom layers.
Holt recommends following the recommended PCB mounting and screw torque specifications, and using a conformal coating to protect the device from moisture and vibration. Additionally, ensure that the PCB is properly secured to the chassis or enclosure.
While the PM-DB2745D has built-in ESD protection, it is not designed to withstand repeated or high-energy ESD events. Additional external ESD protection may be necessary in harsh environments or applications with high ESD risk.
Yes, the PM-DB2745D is designed to support hot-swap applications. However, ensure that the power supply is properly sequenced and that the device is properly bypassed during hot-swap events to prevent damage.
Holt recommends a power-up sequence of VCC, followed by VIO, and then the clock signal. This ensures proper device initialization and prevents potential latch-up or damage.
