TD62064BP-1/BF
TOSHIBA BIPOLAR DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC
TD62064BP-1,TD62064BF
4CH HIGHCURRENT DARLINGTON SINK DRIVER
The TD62064BP1 and TD62064BF are highvoltage,
highcurrent darlington drivers comprised of four NPN
darlington pairs. All units feature integral clamp diodes for
switching inductive loads.
Applications include relay, hammer, lamp and stepping motor
drivers.
FEATURES

SCHEMATICS (EACH DRIVER)
TD62064BP-1/BF
Note : The input and output parasitic diodes cannot be used as clamp diodes.
PRECAUTIONS for USING
(1) This IC does not include built-in protection circuits for excess current or overvoltage.
If this IC is subjected to excess current or overvoltage, it may be destroyed.
Hence, the utmost care must be taken when systems which incorporate this IC are designed.
Utmost care is necessary in the design of the output line, COMMON and GND line since IC may be destroyed
due to shortcircuit between outputs, air contamination fault, or fault by improper grounding.
(2) If a TD62064BP-1/BF is being used to drive an inductive load (such as a motor, solenoid or relay), Toshiba
recommends that the diodes (pins 1 and 8) be connected to the secondary power supply pin so as to absorb the
counter electromotive force generated by the load. Please adhere to the device’s absolute maximum ratings.
Toshiba recommends that zener diodes be connected between the diodes (pins 1 and 8) and the secondary
power supply pin (as the anode) so as to enable rapid absorption of the counter electromotive force. Again,
please adhere to the device’s absolute maximum ratings.
