Frequently Asked Questions
What peak gate-drive current can TPS28225TDRBRQ1 deliver, and how does this affect high-frequency MOSFET switching?
The TPS28225TDRBRQ1 provides 4 A sink current per channel, enabling it to discharge MOSFET gate capacitance of 10 nF in under 10 ns during turn-off transitions. This fast discharge reduces switching losses at frequencies above 500 kHz, making the driver suitable for automotive synchronous buck regulators where high switching speed is needed to achieve compact 10 µH inductor designs.
Which automotive temperature and qualification requirements does the TPS28225TDRBRQ1 satisfy for under-hood applications?
The device is AEC-Q100 qualified and rated for junction temperatures from −40°C to 125°C, meeting the thermal stress requirements for under-hood automotive modules. This Grade 1 temperature range covers engine-bay and transmission-control environments where ambient temperatures routinely exceed 85°C, ensuring reliable gate-drive operation across a 165°C total thermal span.
How does the 3-state output feature of TPS28225TDRBRQ1 protect a synchronous buck converter during fault conditions?
The 3-state output tri-states both gate-drive outputs when the enable pin is de-asserted, placing both high-side and low-side MOSFETs into a high-impedance off state within 2 channels simultaneously. This prevents shoot-through during fault shutdown sequences in 12 V automotive battery rails, reducing the risk of MOSFET damage and simplifying fault-handling logic in body-control and ADAS power modules.
