FAN7080_F085 Half Bridge Gate Driver Features Description * Qualified to AEC Q100 The FAN7080_F085_F085 is a half-bridge gate drive IC with reset input and adjustable dead time control. It is designed for high voltage and high speed driving of MOSFET or IGBT, which operates up to 600V. Fairchild's high-voltage process and common-mode noise cancellation technique provide stable operation in the high side driver under high-dV/dt noise circumstances. An advanced level-shift circuit allows high-side gate driver operation up to VS=-5V (typical) at VBS=15V. Logic input is compatible with standard CMOS outputs. The UVLO circuits for both channels prevent from malfunction when VCC and VBS are lower than the specified threshold voltage. Combined pin function for dead time adjustment and reset shutdown make this IC packaged with space saving SOIC-8 Package. Minimum source and sink current capability of output driver is 250mA and 500mA respectively, which is suitable for junction box application and half and full bridge application in the motor drive system. * Floating channel designed for bootstrap operation fully operational to + 600V * Tolerance to negative transient voltage on VS pin * VS-pin dv/dt immune. * Gate drive supply range from 5.5V to 20V * Under-voltage lockout * CMOS Schmitt-triggered inputs with pull-down * High side output in phase with input * IN input is 3.3V/5V logic compatible and available on 15V input * Matched propagation delay for both channels * Dead time adjustable SOIC-8 Typical Applications * Junction Box * Half and full bridge application in the motor drive system Ordering Information Device Package Operating Temp.

Vdd is output voltage of Microcontroller. The operating range that allows a VDT range of 1.2~3.3V. When pulled lower than V DT [Typ. 0.5V] the device is shutdown. Care must be taken to avoid below threshold spikes on pin 3 that can cause undesired shut down of the IC. For this reason the connection of the components between pin 3 and ground has to be as short as possible. And a capacitor (Typ 0 .02 uF )between pin3 and COM can prevent this spike. This pin can not be left floating for the same reason. 6 FAN7080_F085 Rev. 1.0.2 www.fairchildsemi.com FAN7080_F085 Half Bridge Gate Driver Typical Application Circuit VCC=VBS=15V, -40 C < tj < 125C 3000 Dead Time(ns) 2500 IN 2000 1500 1000 500 Max.

ANTI-COUNTERFEITING POLICY Fairchild Semiconductor Corporation's Anti-Counterfeiting Policy. Fairchild's Anti-Counterfeiting Policy is also stated on our external website, www.fairchildsemi.com, under Sales Support. Counterfeiting of semiconductor parts is a growing problem in the industry. All manufacturers of semiconductor products are experiencing counterfeiting of their parts. Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failed applications, and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the proliferation of counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild Distributors who are listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild Distributors are genuine parts, have full traceability, meet Fairchild's quality standards for handling and storage and provide access to Fairchild's full range of up-to-date technical and product information. Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address any warranty issues that may arise. Fairchild will not provide any warranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is committed to combat this global problem and encourage our customers to do their part in stopping this practice by buying direct or from authorized distributors.
