Functional description
6.1
Device power-up
At power-up end, the device state is the following:
●
Registers are set to default,
●
Internal logic is driven by internal oscillator and a 2MHz clock is provided by OSCOUT
pin,
●
Bridges are disabled (High Z),
●
UVLO bit in STATUS register is forced low (fail condition),
●
FLAG output is forced low
During power-up the device is under reset (all logic IO disabled and power bridges in high
impedance state) until the following conditions are satisfied:
●
VS is greater than VSthOn,
●
VREG is greater than VREGth,
●
Internal oscillator is operative.
Any motion command makes the device exiting from High Z state (HardStop and SoftStop
included).
6.2
Logic I/O
Pins CS, CK, SDI, STCK, SW and STBY are TTL/CMOS 3.3V-5V compatible logic inputs.
Pin SDO is a TTL/CMOS compatible logic output. VDD pin voltage sets the logic output pins
voltage range.
A 10F capacitor should be connected to VDD pin in order to obtain a correct operation.
Pins FLAG and BUSY are open drain outputs.
6.3
Charge pump
To ensure the correct driving of the high side integrated mosfets a voltage higher than the
motor power supply voltage needs to be applied to the VBOOT pin. The high side gate
driver supply voltage Vboot is obtained through an oscillator and a few external components
realizing a charge pump (see Figure 4).
