Product Details
AOZ32033AQI - Integrated Half-Bridge Coil Driver Power Stage
AOZ32033AQI from Alpha & Omega Semiconductor Inc. is an integrated half-bridge gate driver and 30 V N-channel MOSFET power stage with adjustable slew-rate control for wireless-power and motor-drive bridges.
Specifications were checked against the manufacturer data sheet and current distributor listing.
Overview
AOZ32033AQI combines high-side and low-side 11 mOhm MOSFETs, their gate driver, bootstrap diode and programmable source/sink current in a thermally enhanced 3 x 3 mm QFN.
Key Advantages
Reduces bridge component count and PCB area compared with a discrete driver and MOSFET solution.
Adjustable slew control balances switching loss against EMI in resonant wireless-power and motor applications.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.
Feature Summary
High-current half-bridge switching for coils and motors
Independent high-side and low-side logic inputs plus analog slew-rate control
3.8 V to 28 V input; up to 7 A output; -40 C to +85 C
18-PowerWFQFN
Package & Footprint
This ordering code uses the 18-PowerWFQFN package.
Pin Functions
Confirm exact numbering and the latest land pattern before PCB release.
