This allows for N-Channel MOSFET control in half-bridge, full-bridge, two-switch forward and active clamp forward converters. The low-side and the high-side gate drivers are independently controlled and matched to 1-ns between the turn-on and turn-off of each other. The UCC27201A-Q1 is based on the popular UCC27200 and UCC27201 drivers, but offer some enhancements. In order to improve performance in noisy power supply environments the UCC27201AQ1 has the ability to withstand a maximum of -18 V on its HS pin. 1 • • • • • • • • • • • • Qualified for Automotive Applications AEC-Q100 Qualified With the Following Results: – Device Temperature Grade 1: –40°C to 140°C Ambient Operating Temperature Range – Device HBM Classification Level 1C – Device CDM Classification Level C3 Negative Voltage Handling on HS (–18 V) Drives Two N-Channel MOSFETs in HighSide/Low-Side Configuration Maximum Boot Voltage: 120 V Maximum VDD Voltage: 20 V On-Chip 0.65-V VF, 0.6-Ω RD Bootstrap Diode Greater than 1 MHz of Operation 20-ns Propagation Delay Times 3-A Sink, 3-A Source Output Currents 8-ns Rise and 7-ns Fall Time with 1000-pF Load 1-ns Delay Matching Under Voltage Lockout for High-Side and LowSide Driver Offered in 8-Pin PowerPad™ SOIC-8 (DDA) and 10-Pin VSON (DMK) Packages An on-chip bootstrap diode eliminates the external discrete diodes. Under-voltage lockout is provided for both the high-side and the low-side drivers forcing the outputs low if the drive voltage is below the specified threshold. The UCC27201A-Q1 has TTL-compatible thresholds and is offered in a 10-Pin VSON and an 8-pin SOIC with a thermal pad.

Pin Functions PIN NAME DDA DMK I/O (1) DESCRIPTION HB 2 2 P High-side bootstrap supply. The bootstrap diode is on-chip but the external bootstrap capacitor is required. Connect positive side of the bootstrap capacitor to this pin. Typical range of HB bypass capacitor is 0.022 μF to 0.1 μF, the value is dependant on the gate charge of the high-side MOSFET however. HI 5 7 I High-side input. HO 3 3 O High-side output. Connect to the gate of the high-side power MOSFET. HS 4 4 P High-side source connection. Connect to source of high-side power MOSFET. Connect negative side of bootstrap capacitor to this pin. LI 6 8 I Low-side input. LO 8 10 O Low-side output. Connect to the gate of the low-side power MOSFET. N/C – 5/6 - No connection. Pins labeled N/C have no connection. Pad (2) Pad (2) G Connect to a large thermal mass trace or GND plane to dramatically improve thermal performance. VDD 1 1 P Positive supply to the lower gate driver. De-couple this pin to VSS (GND). Typical decoupling capacitor range is 0.22 μF to 1.0 μF.
