HIP4020

Half Amp Full Bridge Power Driver for Small 3V, 5V and 12V DC Motors

DATASHEET

In the Functional Block Diagram of the HIP4020, the four

switches and a load are arranged in an H-Configuration so

that the drive voltage from terminals OUTA and OUTB can

be cross-switched to change the direction of current flow in

the load. This is commonly known as 4-quadrant load

control. As shown in the Block Diagram, switches Q1 and Q4

are conducting or in an ON state when current flows from

with respect to OUTB. Switches Q1 and Q4 are operated

synchronously by the control logic. The control logic

switches Q3 and Q2 to an open or OFF state when Q1 and

Q4 are switched ON. To reverse the current flow in the load,

the switch states are reversed where Q1 and Q4 are OFF

while Q2 and Q3 are ON. Consequently, current then flows

potential with respect to OUTA.

Terminals ENA and ENB are ENABLE Inputs for the Logic A

and B Input Controls. The ILF output is an Overcurrent Limit

Fault Flag Output and indicates a fault condition for either

Supply reference terminals for the A and B Control Logic

terminal is internally connected to each bridge driver, the

the gate drive circuitry to the NMOS (low-side) output stages

allows controlled level shifting of the output drive relative to

ground.
