CS4161
85 mA Dual H-Bridge
Odometer Driver with
Divide by Select and UVLO
The CS4161 is a Stepper Motor Driver that implements an
H–Bridge design in order to drive two coils in an eight step sequence
per revolution in the divide by 1 mode; 16 step sequence in the divide
by 2 mode. The H–Bridge is capable of delivering 85 mA to the load.
The sequencer insures that the odometer is monotonic. This
sequencer is configured such that simultaneous conduction does not
occur. Before each successive output sequence the part is taken
through a state where both outputs are turned off individually. This
tends to minimize the inductive kick back energy that the part must
absorb. On chip clamp diodes are across each output to protect the part
from the kick back energy that it must absorb.

MARKING DIAGRAM
The CS4161 includes overvoltage and short circuit protection
circuitry. It is lead for lead compatible with the CS8441. The CS4161
includes an additional undervoltage lockout (UVLO) function which
disables the output stage until the supply voltage rises above 5.6 V,
typically. The UVLO has hysteresis to prevent any power up glitching.

DIVIDER SELECT INPUT
The speed sensor input frequency is either divided by one
or divided by two depending on the state of the SELECT
input as follows:

Simultaneously energizing the source and sink on either
leg is not permitted, i.e. Q1 & Q2 or Q3 & Q4 cannot be
energized simultaneously.
Logic 0 = divide by 2.
Logic 1 = divide by 1.
Circuit function is not affected by inductive transients due
to coil loads as specified in the Transition States section.
The transition states occur as indicated in Table 1 without
any intermediate states permitted.
