MIC2981/2982

High-Voltage High-Current Source Driver Array

Preliminary Information

General

Features

The MIC2981/82 is an 8-channel, high-voltage, high-current

source driver array ideal for switching high-power loads from

logic-level TTL, CMOS, or PMOS control signals.

• Output voltage to 50V

• Output current to 500mA

• Transient-protected outputs

• Integral clamp diodes

These drivers can manage multiple loads of up to 50V and

500mA, limited only by package power dissipation.

• TTL, CMOS, or PMOS compatible inputs

Applications

• Relay and solenoid switching

• Stepping motor

Micrel’s MIC2981/82 features inputs compatible with 5V TTL

and 5V to 15V CMOS or PMOS logic outputs. Micrel’s dual-

marked device replaces either UDN2981 or UDN2982 de-

vices.

• LED and incandescent displays

The MIC2981/82 is available in the 18-pin plastic DIP and 18-

lead wide SOP package. Both devices operate in the indus-

trial temperature range.
