TA8069F

TA8069F TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC TA8069F 4CH LOW SIDE DRIVER TA8069F is built into four 0.5A low-side driver ICs which drive lamp, relay, and solenoid actuators. Inputs from DI1, DI2, DI3, and DI4 switch ON and OFF modes. Inputs are TTL-compatible, thus the device can also be directly controlled from a CPU or other control system. The device is equipped with low-standby (with all outputs off), self-diagnosis, and protection functions. FEATURES l 0.5A low-side driver l Four built-in circuits (power supply, self−diagnosis, and protection functions for each circuit) l Low standby current 0.1mA (Max.) l Self-diagnosis output Short : 1A (Typ.) DＧ1 : OR output of OUT1 & OUT2 DＧ2 : OR output of OUT3 & OUT4 l Recommended operating supply voltage range: VCC = 8 V to 16 V l Multiple protection functions Short, thermal, and overvoltage protection functions l Built-in diodes for absorbing counter electromotive force l HSOP-20pin power flat package Weight: 0.79 g (typ.) 1 2002-02-27 TA8069F BLOCK DIAGRAM AND PIN ASSIGNMENT DI3 NC DI4 L･G2 DG2 OUT4 P･G2 NC OUT3 VCC2 20 19 18 17 16 FIN 15 14 13 12 11 CONTROL LOGIC OVER-VOLTAGE PROTECTION OVER-VOLTAGE PROTECTION CONTROL LOGIC DIAG CONTROL THERMAL PROTECTION DIAG CONTROL SHORT PROTECTION SHORT PROTECTION 1 2 3 4 5 FIN 6 7 8 9 10 DI1 NC DI2 L･G1 DG1 OUT2 P･G1 NC OUT1 VCC1 PIN DESCRIPTION PIN No. 1, 20 3, 18 4, 17 5, 16 6, 15 9, 12 7, 14 10, 11 2, 8, 13, 19 SYMBOL DESCRIPTION DI1, DI3 DI2,...
