TD62S351AFM 2001-12-05 1 toshiba bipolar digital integrated circuit silicon monolithic TD62S351AFM 1-channel darlington source-current driver the TD62S351AFM is a 1-channel inverting source-current driver with pnp transistor at the first stage and a npn darlington transistor at the second stage. the driver incorporates an input resistor which limits output pull-down resistance and base current. because the driver operates by source input current, it is optimal for interfacing with sink-current driven general-purpose cmos logic ics and microprocessors. also, the driver is optimal for driving fluorescent display tubes and leds. when using the driver, pay attention to the thermal conditions. features ultra-small hson6 package with heat sink on rear large output voltage: v out = ? 50 v (min) large output current: i out = ? 500 ma (max) built-in input resistor: r in = 14 k ? input signal: low level active pin connection (top view) basic circuit diagram note 1: diodes shown using dotted lines are parasitic. do not use them. note 2: when using the driver, connect the output pin to the test pin. note 3: when using the driver, connect the p-gnd pin to the heat sink on the rear of the package. weight: 0.017 g (typ.) 1 2 3 input p-gnd nc 6 5 4 output test v cc input 14 k v cc test output p-gnd 5 k 10 k rpd 7 k
