Description
The FOD8316 is an advanced 2.5A Output Current
IGBT Drive Optocoupler, capable of driving most 1200V/
150A IGBTs. It is ideally suited for fast switching driving
of power IGBTs and MOSFETs used in motor control
inverter applications and high performance power
systems. It offers critical protection features necessary
for preventing fault conditions that lead to destructive
thermal runaway of IGBTs.
It utilizes Fairchild’s patented coplanar packaging
technology, Optoplanar®, and optimized IC design to
achieve high noise immunity, characterized by high
common mode rejection and power supply rejection
specifications.
It consists of an integrated gate drive optocoupler featur-
ing low RDS(ON) CMOS transistors to drive the IGBT from
rail to rail and an integrated high speed isolated feed-
backwww.DataSheet.net/ for fault sensing. The device is housed in a com-
pact 16-pin small outline plastic package which meets
the 8mm creepage and clearance requirements.

Notes:
10. Maximum pulse width = 10µs, maximum duty cycle = 0.2%.
11. Maximum pulse width = 4.99ms, maximum duty cycle = 99.8%.
12. VOH is measured with the DC load current in this testing (Maximum pulse width = 1ms,
Maximum duty cycle = 20%).When driving capacitive loads, VOH will approach VDD as IOH approaches zero units.
13. Positive Output supply voltage (VDD2 – VE) should be at least 15V. This is to ensure adequate margin in excess of
the maximum Under Voltage Lockout Threshold VUVLO+ of 13.5V.
14. When VDD2 – VE > VUVLO and output state VO of the FOD8316 is allowed to go high, the DESAT detection feature
will be active and will provide the primary source of IGBT protection. UVLO is needed to ensure DESAT detection
is functional.
15. The blanking time, tBLANK is adjustable by an external capacitor (CBLANK) where tBLANK = CBLANK * (VDESAT/ICHG)
