Part Name(s) : 2962 UDN2962 UDN2962W Allegro
Allegro MicroSystems
Description : DUAL SOLENOID/MOTOR DRIVER PULSE-WIDTH MODULATED CURRENT CONTROL View

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.

FEATURES
■ 4 A Peak Output
■ 45 V Min. Sustaining Voltage
■ Internal Clamp Diodes
■ TTL/PMOS/CMOS Compatible Inputs
■ High-Speed Chopper

Part Name(s) : CA3275 CA3275E Intersil
Intersil
Description : DUAL Full Bridge Driver View

Description
The CA3275 DUAL Full Bridge Driver is intended for generalpurpose applications requiring DUAL Full Bridge drive or switching, including direction and PULSE-width modulation for position control. While all features of the IC may not be utilized or required, they would normally be used in instrumentation systems with quadrature coils, such as air-core gauges, where the coils would be driven at frequencies ranging from 200Hz to 400Hz. The coils are wrapped at 90o angles for independent direction control. Coils wound in this physical configuration are controlled by PULSE width modulation, where each coil drive is a function of the sine or cosine versus degrees of movement. The direction control is used to change the direction of the current in the H-Driver coil.

Features
• Two Full Bridge Drivers
• ± 150mA Maximum Current
• Logic Controlled Switching
• Direction Control
• PWM IOUT Control
• 18V Over-Voltage Protection
• 300mA Short-Circuit Protection
• Nominal 8V to 16V Operation
• Internal Voltage Regulation With Bandgap Reference

Applications
DUAL Full Bridge Driver For Air Core Gauge Instrumentation
• µP Controlled Sensor Data Displays
• Speedometer Displays
• Tachometer Displays
• Stepper Motors
• Slave Position Indicators


Part Name(s) : MM88C29 MM88C29N MM88C30 MM88C30M MM88C30MX MM88C30N Fairchild
Fairchild Semiconductor
Description : Quad Single-Ended Line Driver • DUAL Differential Line Driver View

General Description
The MM88C30 is a DUAL differential line driver that also performs the DUAL four-input NAND or DUAL four-input AND function. The absence of a clamp diode to VCC in the input protection circuitry of the MM88C30 allows a CMOS user to interface systems operating at different voltage levels. Thus, a CMOS digital signal source can operate at a VCC voltage greater than the VCC voltage of the MM88C30 line driver. The differential output of the MM88C30 eliminates ground-loop errors.
The MM88C29 is a non-inverting single-wire transmission line driver. Since the output ON resistance is a low 20Ω typ., the device can be used to drive lamps, relays, solenoids, and clock lines, besides driving data lines.

Features
■ Wide supply voltage range: 3V to 15V
■ High noise immunity: 0.45 VCC (typ.)
■ Low output ON resistance: 20Ω (typ.)
