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.
•
•
•
•
•
These drivers can manage multiple loads of up to 50V and
500mA, limited only by package power dissipation.
Micrel’s MIC2981/82 features inputs compatible with 5V TTL
and 5V to 15V CMOS or PMOS logic outputs. Micrel’s dualmarked device replaces either UDN2981 or UDN2982 devices.
The MIC2981/82 is available in the 18-pin plastic DIP and 18lead wide SOP package. Both devices operate in the industrial temperature range.
Output voltage to 50V
Output current to 500mA
Transient-protected outputs
Integral clamp diodes
TTL, CMOS, or PMOS compatible inputs
Applications
• Relay and solenoid switching
• Stepping motor
• LED and incandescent displays
