The Multi-Mount Continuous Monitor is a real time

instrument that ensures that critical ESD generators in a

sensitive area are effectively grounded. The instant an

operator’s wrist strap or cord fails, the monitor will issue

audible and visual (LEDs) alarms alerting the user and

supervisor of the problem.

The Parking Snap features provides a means for the

operator to disconnect wrist strap cord when normally

leaving work area without audible alarm sounding. It also

provides a means of wrist strap storage.

ADVANTAGES OF CONTINUOUS MONITORING

OVER PERIODIC TESTING

Many customers are eliminating periodic testing and

are utilizing continuous monitoring to better ensure that

their products were manufactured in an ESD protected

environment. Full time continuous monitoring is superior

to periodic or pulsed testing, and can save a significant

Literature Number: SNVS091E

/LMD182003A, 55V H-BridgeGeneral DescriptionThe LMD18200 is a 3A H-Bridge designed for motion controlapplications. The device is built using a multi-technology pro-cess which combines bipolar and CMOS control circuitry withDMOS power devices on the same monolithic structure. Idealfor driving DC and stepper motors; the LMD18200 accom-modates peak output currents up to 6A. An innovative circuitwhich facilitates low-loss sensing of the output current hasbeen implemented.Features■Delivers up to 3A continuous output■Operates at supply voltages up to 55V■Low RDS(ON) typically 0.33Ω per switch at 3A■TTL and CMOS compatible inputs■No “shoot-through” current■Thermal warning flag output at 145°C■Thermal shutdown (outputs off) at 170°C■Internal clamp diodes■Shorted load protection■Internal charge pump with external bootstrap capabilityApplications■DC and stepper motor drives■Position and velocity servomechanisms■Factory automation robots■Numerically controlled machinery■Computer printers and plottersFunctional Diagram
