Basic Circuitry
Integrated circuit, U6805B, requires a stabilized supply
voltage (V
S
= 5 V
5%) to comply with its electrical
characteristics. An external buffer capacitor of C = 100 nF
value is recommended. An integrated 14-V Z-diode
between V
S
and ground protects the supply pin.
All input stages are provided with an integrated 250 k
pull–up resistor and can be directly connected to a micro-
controller.
All output stages are open collectors each capable of
sinking 20 mA. Recommended external components:
Pull–up resistor, R = 1 k
Capacitor to GND, C = 470 pF, see figure 3
Functional Description
General
ON state: Low level at the input stage activates the
corresponding output stage.
OFF state: The internal pull-up resistor gives high level
to the input comparator and deactivates the output stage.
7-V Z-diodes between each input pin and GND are
capable of
10 mA clamping currents without crosstalk
on adjacent input stages.
A total clamping current of
with respect to the power dissipation.
30 mA should be observed
Current Limitation of the Output
Stages and Overtemperature
Shut-down
A temperature dependent current limitation between
25 and 100 mA protects the stages during a short.
Additionally the chip temperature is monitored. For T
chip
> 148 C all outputs are disabled and automatically
enabled with a hysteresis of TChip > 5 K.
Refer to hexdriver U6807B if the temperature shut down
is not required.
Transients and Load-Dump
An integrated 28-V Z-diode protects each output stage
against transients and load-dump (Schaffner pulses).
With the help of external 1-k resistor , the output
transistor is capable of the corresponding current which
flows during each of these conditions. Apart from that,
outputs are short circuit and overload protected.
Low Voltage Detection
When supply voltage is switched on, a power-on reset
pulse is generated internally, which disables all output
stages until a defined supply voltage level is reached. The
low voltage detection is provided with a hysteresis of
V
hyst
= 0.5 V typically.
