TD62445FN

TD62445FN TOSHIBA BIPOLAR DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC TD62445FN LOW−SATURATION−TYPE SINK DRIVER WITH 4−CIRCUIT OVER−CURRENT DETECTION FUNCTION The TD62445FN is a sink driver with over−current detector circuits. Each of four circuits can setting the limit current. Using an internal comparator, the TD62445FN 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 l Includes current limiter circuits: By connecting external resistors, each bit can be set to any limit current value. Weight: 0.08 g (Typ.) l Includes an error detection signal filter pin: Connecting any capacitor between the LP pin and the GND filters the internal comparator detection signal and outputs this to the ERR pin. l Over−current monitor detection output: Includes an ERR pin output to warn when current exceeds the limit. Construct a system so that the input signal turns off immediately the ERR pin comes on (open collector). l Common input pin (CO−IN (pin 4)) : Using this pin, the four over−current detector circuits can be forcibly turned off together. l Low−saturation−type output (open collector): The voltage drop between the collector and emitter is VOL1 = 0.4 V (max) @ IO = 100 mA. l Supply voltage : VCC = 4.5 to 5.5 l Input is TTL compatible. l U...
