3 Description
The TPIC6B595 device is a monolithic, high-voltage,
medium-current power 8-bit shift register designed for
use in systems that require relatively high load power.
The device contains a built-in voltage clamp on the
outputs for inductive transient protection. Power
driver applications include relays, solenoids, and
other medium current or high-voltage loads.
This device contains an 8-bit serial-in, parallel-out
shift register that feeds an 8-bit D-type storage
register. Data transfers through the shift and storage
registers on the rising edge of the shift-register clock
(SRCK) and the register clock (RCK), respectively.
The storage register transfers data to the output
buffer when shift-register clear (SRCLR) is high.
When SRCLR is low, the input shift register is
cleared. When output enable (G) is held high, all data
in the output buffers is held low and all drain outputs
are off. When G is held low, data from the storage
register is transparent to the output buffers. 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
serial output (SER OUT) allows for cascading of the
data from the shift register to additional devices.
Outputs are low-side, open-drain DMOS transistors
with output ratings of 50 V and 150-mA continuous
sink-current capability. Each output provides a 500-
mA typical current limit at T_C = 25°C. The current limit
decreases as the junction temperature increases for
additional device protection.
The TPIC6B595 is characterized for operation over
the operating case temperature range of −40°C to
125°C.
