ÿ 16 integrated FET-driver with typ. 0,8Ω RON
The ELMOS IC E910.63A is an 8-fold half-bridge-driver. Two half
ÿ Supply voltage VDD 4.5V to 5.5V
bridge driver outputs can be used to create a full bridge driver.
ÿ Supply voltage VDD2 7.5V to 17V
The load between the two outputs could be, for example, a DC
ÿ Serial μP data interface
motor. These 8 single power half bridges can be used to drive ser-
ÿ Cascadable
vomotors and single ended resistive or inductive loads referenced
ÿ Full duplex serial interface: control on input;
to ground or battery. All loads can be activated at the same time
diagnostic on output
with a continuous current load of 250mA each. In case of only two
ÿ Short-circuit current protection
active half bridges, the continuous current load is increased to
ÿ Short-circuit current limited
500mA each. An over temperature protection circuit is integrated
ÿ Thermal overload-protection
into the IC and deactivates the half bridge outputs (high imped-
(switching all outputs to high impedance)
ance) in case of thermal overload. In case of over current the low
ÿ Under- and over voltage protection
and high side driver of each single half bridge are current limited
ÿ Reverse battery protection (up to 16 V)
and deactivated with a 100ms delay. This information can also be
ÿ Output slew rate limited ( < 200 mV/μs)
read through the diagnosis pin.
