TA8061H 2002-02-27 1 toshiba bipolar linear integrated circuit silicon monolithic TA8061H dual highside driver with diagnosis the TA8061H is a 1.5a highside driver containing two circuits. each circuit has a self - diagnostic function which produces a diagnostic output. the input is ttl - compatible. this ic has other various protective functions features output current capacity : 1.5a diagnostic function : load - open (10ma or less) and over-current (3a or more) detection protective function : short - circuit protection (latch) and thermal - shutdown / over - voltage protection (nonlatch) low standby current : 0.5ma (max.) two circuits contained power package hzip-12pin block diagram and pin layout weight: 4.0 g (typ.)
TA8061H 2002-02-27 2 pin description pin no. symbol description 1, 12 v cc power supply pin. a function for protection against over-voltage is provided so that the output will turn off when the applied voltage exceeds 27.5v (typ.). this function works to protect the ic and load. 2, 11 out pnp-type complementary output pin with a current capacity of 1.5a. when the output pin is supplied with a current exceeding the detection current (typically 3a) because of load short-circuit, the output is latched to the off state to protect the ic. to restart, turn off the input once, then raise it high. 3, 10 diag self-diagnosis detection pin. this signal goes low when the output is short-circuited or opened while the input is on (high). the output will be latched when the load is short-circuited, but will not when the load is opened. this pin supplies an npn open-collector output. 4, 9 in ttl-compatible input pin. the circuit is shown as follows. 5, 8 en when this signal goes high, both channels 1 and 2 are placed in standby state (0.5ma max.). 6, 7 gnd grounded. truth table in out diag normal h h h (on) abnormal l l l (off) D h
