HIGH-CURRENT HALF-BRIDGE MOTOR DRIVER
Designed general-purpose motor driver, UDN2943Z half-bridge driver combines high-current sink source drivers with logic stages, level shifting, diode transient protection, voltage regulator single-supply operation. Capable operating extremely harsh environments, this device withstand high ambient temperatures, output overloads, repeated power supply transient voltages without damage. driver used pairs full-bridge operation, triplets three-phase brushless motordrive applications.

*Internal high-voltage shutdown above
input circuitry compatible with TTL, low-voltage CMOS, NMOS logic. Logic lockout prevents both source sink drivers from turning simultaneously. Each driver turned activelow input, making UDN2943Z especially desirable many microprocessor applications. accidental input open circuit will turn corresponding output. device also provides internallygenerated dead time prevent crossover currents during output switching. Monolithic, space-saving construction offers reliability unobtainable with discrete components. Saturated output drivers provide saturation voltage maximum rated current. Internal short-circuit protection, activated load currents above protects source driver from accidental short-circuits between output ground. UDN2943Z driver rated continuous operation with inductive loads supply voltages With supply voltage transients maximum), high-voltage protection circuit becomes operative, shutting both output drivers. internal thermal shutdown triggered nominal junction temperature 160°C. Single-chip construction 5-lead power-tab TS-001 plastic package provide cost-effective reliable systems designs. also features excellent power dissipation ratings, minimum size, ease installation. heat-sink ground potential does require insulation.
