Dual 2-A High-Speed, Low-Side Gate Drivers FAN3216 / FAN3217 The FAN3216 and FAN3217 dual 2 A gate drivers are designed to drive N channel enhancement mode MOSFETs in low side switching applications by providing high peak current pulses during www.onsemi.com the short sw itching intervals. They are both available with TTL input thresholds. Internal circuitry provides an undervoltage lockout function by holding the output LOW until the supply voltage is within the operating range. In addition, the drivers feature matched internal 8 propagation delays between A and B channels for applications 1 requiring dual gate drives with critical timing, such as synchronous SOIC8 rectifiers. This also enables connecting two drivers in parallel to CASE 751EB effectively double the current capability driving a single MOSFET. The FAN3216/17 drivers incorporate MillerDrive architecture for the final output stage. This bipolarMOSFET combination provides PACKAGE OUTLINE high current during the Miller plateau stage of the MOSFET turnon / turn off process to minimize switching loss, while providing 1 8 railtorail voltage swing and reverse current capability. The FAN3216 offers two inverting drivers and the FAN3217 offers 2 7 two noninverting drivers. Both are offered in a standard 8pin SOIC 3 6 package. 4 5 Features IndustryStandard Pinouts Figure 1.
