OPERATIO
Operation can best be understood by referring to the
Block Diagram which illustrates the internal circuit blocks.
The LTC4416/LTC4416-1 are divided into three sections,
namely:
1. The channel 1 controller consisting of A1, C1, the “first
analog contoller,” the G1 drivers and the H1 output
driver.
2. The band-gap reference
3. The channel 2 controller consisting of A2, C2, t he
“second analog controller,” the G2 drivers and the H2
output driver.
Each of the three sections has its own derived internal
power supply referred to as a rail. RAIL1 provides power
to the channel 1 controller. RAIL2 provides power to the
channel 2 controller. The internal RAILBG provides power
to the band-gap reference. The internal rail1 derives its
power from the higher voltage of V1 and V S . The internal
rail2 derives its power from the higher voltage of V2 and
V S . RAILBG derives its power from the highest voltage of
V1, V2, and V S . All three sections share a common ground
connected to the GND pin.
