CS1107
CIRCUIT DESCRIPTION
The CS1107 relay driver IC provides up to 350 mA of
drive current in a low–side configuration. The Output driver
pin is controlled through the TTL compatible Control input
pin. A high condition on the Control pin turns the output pin
on.
The Fault pin reports short circuit, open circuit, and
overtemperature conditions on the IC. If a fault is present,
the open collector output Fault pin will be low. Typical
numbers for faults are: exceeding 500 mA of drive current
will report a short circuit. Less than 40 mA (typical) will
report an open circuit. A temperature fault will be reported
when the die temperature exceeds 180°C (typical). Faults
are only reported when the Control pin is high, due to the low
quiescent current when the Control pin is low and the output
device is turned off.
Overcurrent protection is provided by duty cycle control.
When the Output current exceeds the current limit threshold,
the output enters duty cycle mode to reduce power
dissipation of the IC to a safe level. The higher the threshold
is exceeded the lower the duty cycle becomes.
A 33 V on–chip zener diode on the Output pin protects the
device from flyback pulses when a relay is turned off. The
saturation voltage of this pin will not exceed 1.5 V at 350 mA.
