BTS730
PWM Power Unit
The device allows continuous power control for lamps,LEDs
or inductive loads.
! Highside switch (Bootstrap)
! 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
