june 2006 rev 2 1/15 15 features high output current adjustable short-circuit protection to ground internal thermal protection with hysteresis to avoid the intermediate output levels large supply voltage range: 8 to 30v short-circuit protection to v cc open ground protection description the tde3247 is a monolithic amplifier designed for high current and high voltage applications, specifically to drive lamps, relays and stepping motors. the device is essentialy blow-out proof. current limiting is available to lim it the peak output current to a safe value, the adjustment only required an external resistor. in addition, thermal shut-down is provided to keep the ic from overheating. if external dissipation becomes too high, the driver will shut-down to prevent excessive heating. the output is also protected against short-circuit with the positive power supply. the device operates over a wide range of supply voltage from standard 15v operational amplifier supplies down to the single 12v or 24v used for industrial electronic systems. so-14 tde3247 interface circuit (relay and lamp driver) www.st.com order codes part number package packaging TDE3247FP so-14 tube TDE3247FPt so-14 tape & reel
