2962

Using PWM to minimize power dissipation and maximize load

efficiency, the UDN2962W dual driver is recommended for impact

printer solenoids and stepper motors. It is comprised of two source/

sink driver pairs rated for continuous operation to

±3

A. It can be

connected to drive two independent loads or a single load in the full-

bridge configuration. Both drivers include output clamp/flyback

diodes, input gain and level shifting, a voltage regulator for single-

supply operation, and pulse-width modulated output-current control

circuitry. Inputs are compatible with most TTL, DTL, LSTTL, and

low-voltage CMOS or PMOS logic.

NOTE: Output current rating may be limited by

duty cycle, ambient temperature, and heat

sinking. Under any set of conditions, do not

exceed the specified peak current and a junction

temperature of +150°C.

LOGIC

The peak output current and hysteresis for each source/sink pair is

set independently. Output current, threshold voltage, and hysteresis are

set by the user’s selection of external resistors. At the specified output-

current trip level, the source driver turns off. The internal clamp diode

then allows current to flow without additional input from the power

supply. When the lower current trip point is reached, the source driver

turns back on.

The UDN2962W is in a 12-pin single in-line power-tab package.

The tab is at ground potential and needs no insulation. For high-

current or high-frequency applications, external heat sinking may be

required.
