BTS730

BTS 730 PWM Power Unit The device allows continuous power control for lamps,LEDs or inductive loads. Highside switch Overtemperatur protection Short circuit / overload protection through pulse width reduction and overload shutdown Load dump protection Undervoltage and overvoltage shutdown with auto-restart and hysteresis Reverse battery protection 1) Timing frequency adjustable Controlled switching rise and fall times Maximum current internally limited Protection against loss of GND 2) Electrostatic discharge (ESD) protection Package: P-DSO-20-6 (SMD) Note: Switching frequency is programmed with an external capacitor.
