PWM RELAY/SOLENOID DRIVER

Rev F1, Page 1/9

FEATURES

APPLICATIONS

♦ Wide operating voltage range of 10 to 45 Vdc

♦ PWM control for coil currents of 40 to 300 mA

♦ Coil current for energise and hold modes set by an external

resistor

♦ PWM drive for inductive loads

(e.g. relays, electrovalves)

♦ Relay low-/high-side switch

♦ Coil current monitored during energise mode, detection of load

breakage and voltage errors

♦ Automatic current reduction after 100 ms to reduce the power

consumption in hold mode

♦ The internal free-wheeling alteration function supports PWM

operation and quick demagnetising during shutdown

♦ Status signalled at the current-limited LED output

♦ Shutdown with excessive temperature and low voltage

♦ Integrated oscillator needs no external components

♦ PWM frequency is beyond audible range

PACKAGES

♦ Protective circuitry against damage by ESD

♦ Minimum space requirements, few external components
