Hello,
Please answer following questions.
< Q1 >
Datasheet title is “15V/±4A High-Efficiency PWM Power Driver”.
What is the meaning of “15V” ?
< Q2 >
Question about “VICM Input common-mode range”.
Datasheet P4 specify “VICM Input common-mode range: 0.5V min, 4.5V max”.
But DRV595EVM User’s Guide(SLAU479) P4 explain as follows.
(P4) Inputs and Outputs
• Connect a dc control voltage to (IN+) ranging from 0.5-V to 5.5-V. Alternately, the terminal (IN+) can be
held to a fixed voltage with a resistor voltage divider, as shown in the schematic.
Input range max is 5.5V and different with datasheet 4.5V.
I feel that 0.5-V to 5.5-V input range is symmetrical from 3.0V and good for use, in case of IN- tied to 3.0V same with datasheet P13 explain as follows.
(P13)
DIFFERENTIAL OR SINGLE-ENDED INPUTS
To use the DRV595 with a single-ended source, use a voltage divider to bias IN- to 3.0V, and apply the single-ended signal to IN+.
Please advice correct input voltage range when use “SINGLE-ENDED INPUTS”.
< Q3 >
DRV595 datasheet P13 has table 2c and title is “Recommended Input AC-Coupling Capacitors”.
But Table has “INPUT IMPEDANCE” not Capacitance and should something wrong.
INPUT IMPEDANCE vs. Gain information is in Table 1 and duplicated.
Please advice meanings of Table 2.
<Q4>
Please advice any restriction of SDZ terminal when power-up PVCC and AVCC.
For example SDZ should be low level while power-up or ……
