DESCRIPTION
This STPIC6C595
SOP
TSSOP
is
a
monolithic,
medium-voltage, low current power 8-bit shift
register designed for use in systems that require
relatively moderate load power such as LEDs. The
device contains a built-in voltage clamp on the
outputs for inductive transient protection. Power
driver applications include relays, solenoids, and
other low-current or medium-voltage loads.
The device contains an 8-bit serial-in, parallel-out
shift register that feeds an 8-bit D-type storage
register. Data transfers through both the shift and
storage register clock (SRCK) and the register
clock (RCK), respectively. The device transfers
data out the serial output (SER OUT) port on the
rising edge of SRCK. The storage register
transfers data to the output buffer when shift
register clear (CLR) is high. When CLR is low, the
input shift register is cleared. When output enable
(G) is held high, all data in the output buffer is held
low and all drain output are off. When G is held
low, data from the storage register is transparent
to the output buffer. When data in the output
buffers is low, the DMOS transistor outputs are off.
When data is high, the DMOS transistor outputs
have sink-current capability. The SER OUT allows
for cascading of the data from the shift register to
additional devices.
Output are low-side, open-drain DMOS transistors
with output ratings of 33V and 100mA continuous
sink-current capability. Each output provides a
250 mA maximum current limit at T = 25°C. The
C
current limit decreases as the junction
temperature increases for additional device
protection. The device also provides up to 1.5KV
of ESD protection when tested using the
human-body model and 200V machine model.
The STPIC6C595 is characterized for operation
over the operating case temperature range of
-40°C to 125°C.
