Description
HCPL-3700 HCPL-3760 voltage/current threshold detection optocouplers. HCPL-3760 low-current version HCPL-3700. obtain lower current operation, HCPL-3760 uses highefficiency AlGaAs which provides higher light output lower drive currents. Both devices utilize threshold sensing input buffer which permit control threshold levels over wide range input voltages with single external resistor.
input buffer incorporates several features: hysteresis extra noise immunity switching immunity, diode bridge easy with input signals, internal clamping

HCPL-3700/3760 optocouplers have internal temperature compensated, predictable voltage current threshold points which allow selection external resistor, determine larger external threshold voltage levels. desired external threshold voltage, corresponding typical value obtained from Figure Specific calculation obtained from Equation (1). Specification both Vvoltage threshold levels simultaneously obtained shown Figure determined Equations (3). provide over-current transient protection limiting input current during transient condition. monitoring contacts relay switch, HCPL-3700/3760 combination with used allow specific current conducted through contacts cleaning purposes (wetting current). choice which input voltage clamp level choose depends upon application this device (see Figure recommended that clamp condition used when possible.
clamp condition conjunction with input current feature will ensure extremely input power dissipation. applications where dVCM/dt extremely large (such static discharge), series resistor, RCC, should connected series with protect detector from destructively high surge currents. Note determination RCC. addition, recommended that ceramic disc bypass capacitor 0.01 placed between Pins reduce effect power supply noise. interfacing signals systems, output pass filtering performed with pullup resistor capacitor. This application requires Schmitt trigger gate avoid slow rise time chatter problems. input applications, filter capacitor placed across input terminals either signal transient filtering.
