Description The FAN7385 is a monolithic high side gate drive ICdesigned for high voltage, high speed driving MOSFETsand IGBTs operating up to +600V.
Fairchild’s high-voltage process and common-modenoise canceling technique provide stable operation ofhigh-side drivers under high-dv/dt noise circumstances.
An advanced level-shift circuit allows high-side gatedriver operation up to VS = -9.8V (typical) for VBS = 15V.
The UVLO circuits prevent malfunction when VBS1 andVBS2 are lower than the specified threshold voltage.
Output drivers typically source/sink 350mA/650mA,respectively, which is suitable for dual high-side switchesand half-bridge inverters.

Absolute Maximum RatingsStresses exceeding the absolute maximum ratings may damage the device. The device may not function or be opera-ble above the recommended operating conditions and stressing the parts to these levels is not recommended. In addi-tion, extended exposure to stresses above the recommended operating conditions may affect device reliability. Theabsolute maximum ratings are stress ratings only. TA=25°C, unless otherwise specified.
Notes: 2. Mounted on 76.2 x 114.3 x 1.6mm PCB (FR-4 glass epoxy material).3. Refer to the following standards: JESD51-2: Integral circuits thermal test method environmental conditions - natural convection JESD51-3: Low effective thermal conductivity test board for leaded surface mount packages4. Do not exceed PD under any circumstances.
Recommended Operating ConditionsThe Recommended Operating Conditions table defines the conditions for actual device operation. Recommendedoperating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does notrecommend exceeding them or designing to Absolute Maximum Ratings.

Typical Application Information1. Under-Voltage Lockout (UVLO)The FAN7385 has an under-voltage lockout (UVLO)protection circuit to prevent malfunction when VBS1 andVBS2 are lower than the specified threshold voltage. TheUVLO circuit monitors the bootstrap capacitor voltages(VBS1, VBS2) independently.
2. Layout ConsiderationFor optimum performance, considerations must be givenduring printed circuit board (PCB) layout.
2.1 Supply Capacitors
If the output stages are able to quickly turn on a switch-ing device with a high current value, the supply capaci-tors must be placed as close as possible to the devicepins (VDD and GND for the ground-tied supply, VB andVS for the floating supply) to minimize parasitic induc-tance and resistance.
2.2 Gate Drive Loop
Current loops behave like antennae, able to receive andtransmit noise. To reduce the noise coupling/emissionand improve the power switch turn-on and off perfor-mances, gate drive loops must be reduced as much aspossible.
2.3 Ground Plane
To minimize noise coupling, avoid placing the groundplane under or near the high-voltage floating side.
