Frequently Asked Questions
What is the peak output current of the UCC37321PE4?
The UCC37321PE4 delivers a peak output current of 9 A in both source and sink directions, enabling rapid charging and discharging of MOSFET gate capacitances to minimize switching transition times and reduce power losses.
Is the UCC37321PE4 suitable for high-side gate driving?
No, the UCC37321PE4 is a low-side driver only and does not include a bootstrap or level-shift circuit for high-side operation. For high-side driving, consider pairing it with a dedicated high-side driver or using a half-bridge driver IC.
What supply voltage range does the UCC37321PE4 support?
The UCC37321PE4 operates from a 4.5 V to 15 V supply voltage, making it compatible with a wide range of gate drive voltages used in both logic-level and standard power MOSFET applications in switching power supplies.
What package does the UCC37321PE4 come in?
The UCC37321PE4 is available in an 8-pin PDIP through-hole package, which is convenient for prototyping and breadboarding, as well as for production boards where wave soldering of through-hole components is used.
What is a common alternative to the UCC37321PE4?
A functionally similar alternative is the TC4429 from Microchip Technology, which also provides a single-channel 6 A MOSFET driver. The Texas Instruments UCC27321 offers a surface-mount version with equivalent electrical performance for higher-density PCB designs.
