TD310 TRIPLE IGBT/MOS DRIVER WITH CURRENT SENSE THREE POWER IGBT/MOS AND PULSE TRANSFORMER DRIVERS CURRENT SENSE COMPARATOR UNCOMMITTED OP-AMP 0.6 A PER CHANNEL PEAK OUTPUT CURRENT CAPABILITY N LOW OUTPUT IMPEDANCE TYP: 7 AT DIP-16 200mA (Plastic Package) CMOS/LSTTL COMPATIBLE INVERTING INPUT WITH HYSTERESIS 4V TO 16V SINGLE SUPPLY OPERATION LOW BIAS CURRENT TYP: 1.5mA ADJUSTABLE UNDERVOLTAGE LOCKOUT D SO-16 LEVEL (Plastic Micropackage) STAND-BY MODE CHANNEL PARALLELING CAPABILITY ORDER CODE Package DESCRIPTION Part Number Temperature Range ND The TD310 is designed to drive one, two or three TD310I -40C, +125C Power IGBT/MOS and has driving capability for N = Dual in Line Package (DIP) pulse transformer. So it is perfectly suited to D = Small Outline Package (SO) - also available in Tape & Reel (DT) interface control IC with Power Switches in low side or half-bridge configuration. PIN CONNECTIONS (top view) TD310 includes a current sense comparator which inhibit the output drivers in case of overcurrent. An alarm output signals the even to a controller. VCC 1 16 UVLO/Stby TD310 also includes an uncommitted op-amp INA 2 15 OUTA which can be used for current measurement (as INB 3 14 OUTB an amplifier before the A/D input of a microcontroller) of for other general purpose. INC 4 13 OUTC Programmable undervoltage lockout and standby Enable 5 12 Gnd mode make TD310 suitable for a large area of Alarm 6 11 Sense - environment and application. OA Output 7 10 OA Input - Typical applications are low side IGBT and power MOSFET drive in three phase systems, pulse OA Input + 8 9 Sense + transformer drive, and general purpose pulse drive.
