Procurement Notes
When requesting a quote for UCC27714, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For power IC and power device sourcing, voltage rating, current rating, power dissipation, package thermal performance, protection features, qualification grade and application conditions should be reviewed before approval.
FAQ
What output current does the UCC27714 provide?
The UCC27714 provides 4 A peak source current and 4 A peak sink current on the HO and LO outputs when operated at VDD = 15 V.
What supply range is recommended for UCC27714 operation?
Recommended operating conditions list VDD at 10-17 V and the HB-HS driver bootstrap voltage at 10-17 V. The broader VDD bias supply range stated in the device facts is 10-20 V.
How does the enable input control the outputs?
For the EN/NC pin, a LOW level disables both HO and LO. A HIGH level or a floating enable input enables the HO and LO outputs.
What happens when HI and LI inputs are floating?
The extracted device facts state that HO and LO are held low when the HI and LI input pins are floating.
