IFX52001EJXUMA1

Product Brief IFX52001EJ Constant Current Relay Driver Key Features Once mechanical relay switches and electromagnetic actuators (also known as solenoids) are turned on, current must continuously flow through their coils (hold „„ High coil activation current current) to keep them on. „„ Low hold current „„ Suited for both low- and The IFX52001EJ can reduce the hold current down to the necessary amount to keep the coil on (40mA without EMI) and thus cut overall current consumption. The coil current high-side switches „„ remains stable regardless of changes to the input voltage. Thermally enhanced PG-DSO-8 exposed pad package IFX52001EJ operates over an extended temperature range from -40°C to 125°C and with Key Benefits input voltages up to 30V, making it ideal for harsh industrial environments. „„ Available in a PG-DSO-8 exposed pad package, this device can be mounted on „„ No EMI, unlike PWM relay driving a PCB inside a relay or on an existing system PCB with either a high- or low-side „„ Supporting freewheeling diode Coil current independent from input voltage variations switch, reducing design-in time and providing a migration path to an all-electronic signal path for energy absorption switch design. during switch off Applications „„ Relays –– The IFX52001EJ can be integrated into relay housing or mounted on system PCB –– Relays up to 2000mH coil inductance and 120Ω series resistance can be driven „„ Electromagnetic actuators –– Electric door locks, appliances, hydraulic valves, speaker coils, power relays, pinball/pachinko machines, manufacturing/automation systems [ www.infineon.com/industrial-standard ] Product Brief IFX52001EJ Constant Current Relay Driver IFX52001EJ Supplied by External Source IFX52001EJ Supplied by Freewheeling Resistor High-Side Switch High-Side Switch Input Voltage Relay Freewheeling Resistor RS S Fwd Ctrl Biasing Bandgap CS RF Input Voltage Freewheeling Resistor LR D Delay „„ Operation as switch „„ For activation of e.g. a relay „„ At high input voltage (to limit power IN Driver D IFX52001EJ Constant Current Relay Driver CGND Activation Mode Fwd Ctrl Biasing Bandgap CS LR RF S IN Driver CD Relay CD Delay IFX52001EJ Constant Current CGND Relay Driver Icoil dissipation during high input voltage faults) „„ At low input voltage (minimum drop) Hold Mode „„ Operation as constant current source „„ During operation after activation time has been elapsed Published by Infineon Technologies AG 85579 Neubiberg, Germany © 2011 Infineon Technologies AG.
