TA8061H

TA8061H 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 l Output current capacity : 1.5A l Diagnostic function : Load-open (10mA or less) and over-current (3A or more) detection l Protective function : Short-circuit protection (latch) and thermal-shutdown / over-voltage protection (nonlatch) l Low standby current : 0.5mA (max.) l Two circuits contained l Power package HZIP-12pin BLOCK DIAGRAM AND PIN LAYOUT Weight: 4.0 g (typ.) 1 2002-02-27 TA8061H PIN DESCRIPTION PIN No. 1, 12 2, 11 3, 10 SYMBOL VCC OUT DIAG DESCRIPTION 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. 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. 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 ...
