FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
POWER SUPPLY
The 33800 is designed to operate from 5.0 to 36V on the
VPWR pin. The VPWR pin supplies power to all internal
regulators, analog and logic circuit blocks. The V
DD
supply is
used for setting communication threshold levels and
supplying power to the SO driver. This IC architecture
provides flexible microprocessor interfacing with low
quiescent current Sleep Modes.
POWER-ON RESET (POR)
Applying V
PWR
, V
DD
and EN to the device will cause a
Power On Reset (POR) and place the device in Normal or
Default Mode.
Command register settings from Power-ON Reset (POR)
via V
PWR
or V
DD
are as follows:
All Outputs Off
Inputs Enabled and OR’d with SPI Bit.
PWM Frequency and Duty Cycle Control Disabled.
OSS Open Load Detect Current Enabled.
OSS Outputs with Individual Control.
Control Inputs P1,P3,P5,P7 Enabled and OR’d with the
SPI Bit.
CCD1 Output Off, Diagnostic Pull-up Enabled, DAC = 0.
CCD2 Output Off, Diagnostic Pull-up Enabled, DAC = 0.
Power On Reset circuit incorporates a 0.5
μ
s timer to
prevent high frequency transients from causing a POR.
During the low-voltage condition, internal logic states are
maintained. To guarantee a POR from V
PWR
, the VPWR pin
must be less than 0.2V for greater than 1.0
μ
s.
MODES OF OPERATION
The 33800 has three operating modes, Normal, Sleep and
Default Mode. A discussion on Normal Mode follows.
NORMAL MODE
Normal Mode allows full functional control of the device.
Transferring from Sleep Mode to Normal Mode performs a
POR and resets all internal registers to the POR state. When
entering Normal Mode from Default Mode, no POR is
performed and register states are maintained.
Features programmed in Normal Mode are listed below.
Further explanation of each feature is provided in subsequent
paragraphs.
Programmable PWM Frequency & Duty Cycle
Programmable PWM Drain Fault Threshold
CCD2 Constant Current Dither Frequency and Amplitude
CCD2 DAC Programming
CCD1 Constant Current Dither Frequency and Amplitude
CCD1 DAC Programming
On/Off OSS Open Load Detect Current
Calibration of Timers (
Calibration Command
)
Reset (

No Operation (
NO_OP Command
)
DEFAULT MODE
The Default Mode allows the user to disable all outputs
except the PWM pre-driver. In Default Mode the PWM pre-
driver outputs may only be controlled via the PWM input pins.
All register control bits and fault bits are maintained in Default
Mode, however control for the pre-driver is accomplished
through the PWM pins only.
With the DEFAULT pin HIGH, the device is placed in
Default Mode. When exiting Default Mode, output control
reverts to the internal register settings.
In Default Mode the device operates with the following
parameters.
1. OSS outputs are disabled.
2. CCD1 and CCD2 outputs are disabled.
3. SPI ON/OFF control of GATE DRIVE (GD1 to GD6)
outputs is disabled. PWMx input control is enabled. The
device will operate as programmed prior to Default Mode.
In Default Mode the device retains all register information
and output status information. Normal operation will resume
when the DEFAULT pin transitions low again.
SLEEP MODE
Sleep Mode is entered by placing a logic [0] on the
ENABLE or VDD pins. All outputs are commanded off and the
device enters a low quiescent current state.
