DESCRIPTION
The TDE1737-TDF1737 is a monolithic amplifier
designed for high c urr e n t and high voltage app lic ations, specific all y to drive lam ps , relays and con trol
of stepper mot or s.
This device is essentially blow-out proof. Current
limiting is available to limit the peak output current
to a safe value, the adjustment only requires one external res istor. In addi tion, thermal sh ut down is provided to keep the I.C. from overheating. If internal
dissipation becomes too great, the driver will shut
down to prevent excessive heating.
The output is also protected against short-circuits
with the positive po wer s upply .
The device operates over a wide range of supply
voltages f r om sta n dar d ± 1 5 V op erationa l ampli fier
supplies down to the single + 12 V or + 24 use d for
industrial electronic systems.
