While current-shunt-monitor ICs like the INA168
can be connected to current-shunt resistors at
supply voltages of up to 60 V, the circuit shown
in the figure allows current sensing at even
higher voltages.. . .
High-Current, Low-Voltage Shunt
Electronic Design - Ideas for Design / This
design idea describes a high-current (up to 8 A)
shunt-regulator built around the TLV431
low-voltage, adjustable, precision
shunt-regulator IC. Special attention was paid
to implementing this design as a "two-terminal"
circuit block, greatly. . .
High-voltage adjustable shunt
Electronic Design - Ideas for Design /
Occasionally, the need arises for a variable
shunt regulator capable of high-voltage
operation. At high voltages, multiple
transistors in series overcome safe-operating
area (SOA) limitations much more effectively
than parallel configurations.. . .
