Table 3. 34920 Input Specifications
Name
Description
V1_FB
Voltage feedback for the V1 regulator.
VCC
VCC power input for internal use. The 34920 accepts either 3.3 V ±10% or 5.0 V ±5% for its logic voltage.
V2_FB
Voltage feedback for the V2 regulator.
CS
Serial input register chip select input. Active low.
SCLK
Serial input register clock.
SDI
Serial input register serial data input.
DRxPWM
PWM input for the DC motor driver for either Driver 1 or Driver 2.
DRx_MODE
Selects mode of each motor driver. Step = 1/DC = 0.
The following inputs are through the Serial Input Register
V2_Enable
Enable bit to turn on and off the V2 regulator and the motor drivers. When low (= logic [0]), the V2 regulator and
the motor drivers are turned off and the 34920 is placed in its lowest possible power state. V1 is not affected by
the Enable bit.
DR1_CURR_I1_PHASEA
Second of two inputs that control the current level in the step motor Phase A winding (Driver 1/Step Mode).
DR1_CURR-I0_PHASEA
First of two inputs that control the current level in the step motor Phase A winding (Driver 1/Step Mode).
DR1_DIR_PH_A
Controls the direction of the current flow through Phase A of the step motor; i.e., logic [1] level causes conventional
current flow from DR1A1 to DR1B1 (Driver 1/Step Mode).
DR1_CURR_I1_PHASEB
Second of two inputs that control the current level in the step motor Phase B winding (Driver 1/Step Mode).
DR1_CURR_I0_PHASEB
First of two inputs that control the current level in the step motor Phase B winding (Driver 1/Step Mode).
DR1_DIR_PH_B
Controls the direction of the current flow through Phase B of the step motor. A logic [1] level causes conventional
current flow from DR1A2 to DR1B2 (Driver 1/Step Mode).
DR2_CURR_I1_PHASEA
Second of two inputs that control the current level in the step motor Phase A winding (Driver 2/Step Mode).
DR2_CURR_I0_PHASEA
One of two inputs that control the current level in the step motor Phase A winding (Driver 2/Step Mode).
DR2_DIR_PH_A
Controls the direction of the current flow through Phase A of the step motor. A logic [1] level causes conventional
current flow from DR2A1 to DR2B1 (Driver 2/Step Mode).
DR2_CURR_I1_PHASEB
Second of two inputs that control the current level in the step motor Phase B winding (Driver 2/Step Mode).
DR2_CURR_I0_PHASEB
One of two inputs that control the current level in the step motor Phase B winding (Driver 2/Step Mode).
DR2_DIR_PH_B
Controls the direction of the current flow through Phase B of the step motor. A logic [1] level causes conventional
current flow from DR2A2 to DR2B2 (Driver 2/Step Mode).
