Dual Gauge Driver with
Configurable Response Time
33976
The 33976 is a single-packaged, Serial Peripheral Interface (SPI)
controlled, dual step motor gauge driver integrated circuit (IC). This
monolithic IC consists of four dual output H-Bridge coil drivers and the
associated control logic. Each pair of H-Bridge drivers is used to
automatically control the speed, direction, and magnitude of current
through the two coils of a two-phase instrumentation step motor,
similar to an MMT-licensed AFIC 6405 or Switec MS-X15.xxx motor.
The 33976 is ideal for use in automotive instrumentation systems
requiring distributed and flexible step motor gauge driving. The
device also eases the transition to step motors from air core motors
by emulating the air core pointer movement with little additional
processor bandwidth utilization.

Notes
1. Exceeding voltage limits on Input pins may cause permanent damage to the device.
2. Output continuous output rating so long as maximum junction temperature is not exceeded. Operation at 125°C ambient temperature will
require maximum output current computation using package thermal resistances.
3. ESD1 testing is performed in accordance with the Human Body Model (CZAP = 100 pF, RZAP = 1500 ), ESD2 testing is performed in
accordance with the Machine Model (CZAP = 200 pF, RZAP = 0 ).
4. Pin soldering temperature limit is for 10 seconds maximum duration. Not designed for immersion soldering. Exceeding these limits may
cause malfunction or permanent damage to the device.
5. Freescale’s Package Reflow capability meets Pb-free requirements for JEDEC standard J-STD-020C. For Peak Package Reflow
Temperature and Moisture Sensitivity Levels (MSL),
Go to www.freescale.com, search by part number [e.g. remove prefixes/suffixes and enter the core ID to view all orderable parts. (i.e.
MC33xxxD enter 33xxx), and review parametrics.

Notes
15. Maximum specified time for the 33976 is the minimum guaranteed time needed from the microcontroller.
16. The minimum and maximum value will vary proportionally to the internal clock tolerance. These numbers are based on an ideally
calibrated clock frequency of 1.0 MHz. These are not 100 percent tested.
