HIGH-CURRENT HALF-BRIDGE MOTOR DRIVER

HIGH-CURRENT

HALF-BRIDGE MOTOR DRIVER

Designed for use as a general-purpose motor driver, the

UDN2943Z half-bridge driver combines high-current sink and source

drivers with logic stages, level shifting, diode transient protection, and

a voltage regulator for single-supply operation. Capable of operating

in extremely harsh environments, this device can withstand high

ambient temperatures, output overloads, and repeated power supply

transient voltages without damage. The driver can be used in pairs for

full-bridge operation, or as triplets in three-phase brushless dc motor-

drive applications.

The input circuitry is compatible with TTL, low-voltage CMOS,

and NMOS logic. Logic lockout prevents both source and sink drivers

from turning ON simultaneously. Each driver is turned ON by an active-

low input, making the UDN2943Z especially desirable in many micro-

processor applications. An accidental input open circuit will turn OFF

the corresponding output. The device also provides an internally-

generated dead time to prevent crossover currents during output

switching. Monolithic, space-saving construction offers reliability

unobtainable with discrete components.

Saturated output drivers provide for low saturation voltage at the

maximum rated current. Internal short-circuit protection, activated at

load currents above 1 A, protects the source driver from accidental

short-circuits between the output and ground.

The UDN2943Z driver is rated for continuous operation with

inductive loads at supply voltages of up to 24 V. With supply voltage

transients (to 35 V maximum), a high-voltage protection circuit

becomes operative, shutting OFF both output drivers. The internal

thermal shutdown is triggered by a nominal junction temperature

of 160°C.

Dwg. PP-022-1

ABSOLUTE MAXIMUM RATINGS

Single-chip construction and a 5-lead power-tab TS-001 plastic

package provide cost-effective and reliable systems designs.

It also features excellent power dissipation ratings, minimum size, and

ease of installation. The heat-sink tab is at ground potential and does

not require insulation.
