TD62445FN

The TD62445FN is designed as one kind of low-satuation-type driver with over current detector circuits. Each of four circuit can setting the limit current. Using an internal comparator, this device detects over-current by comparing the current output through the external resistors as voltage. Over current detection is detected by the ERR terminal which is an open collector, comes on.construct a system so that the input signal turns off immediately the ERR pin comes on.

Features of the TD62445FN are:(1)includes current limiter circuits: by connecting external resistors, each bit can be set to any limit current value;(2)over-current monitor detection output;(3)common input pin: using this pin, the four over-current detector circuits can be forcibly turned off together;(4)low-satuation-type output (open collector);(5)supply voltage: Vcc = 4.5 to 5.5 V;(6)input is TTL compatible;(7)ultra-compact package: VSOP 18 pin (0.65 mm pitch);(8)output rating: VCEO = 30 V, Io = 150 mA/ch;(9)packing: embossed taping only.

The absolute maximum ratings of the TD62445FN can be summarized as:(1)power supply voltage: 7.0 V;(2)COM pin voltage: 30.0 V;(3)output voltage: 30.0 V;(4)ERR pin output voltage: 7.0 V;(5)output sink current: 0 to 150 mA;(6)ERR pin sink current: 10 mA;(7)clamp diode forward current: 150 mA;(8)output parasitic diode forward current: 100 mA;(9)power dissipation: 960 mW;(10)operating temperature: -10 to +85 ;(11)storage temperature: -55 to +150 .
