Sice jsem hledal neco uplne jineho, ale narazil
jsem na MCP1630, treba se hodi na ty krokovy motory:
High-Speed, Microcontroller-Adaptable, Pulse Width Modulator
Features
High-Speed PWM Operation (12 ns Current
Sense to Output Delay)
Operating Temperature Range: -40°C to +125°C
• Precise Peak Current Limit (±5%)
CMOS Output Driver (Drives MOSFET Driver or
Low-Side N-channel MOSFET Directly)
• External Oscillator Input (from PICmicro®
Microcontroller)
External Voltage Reference Input (for adjustable
voltage or current output application)
Peak Current Mode Operation to 1 MHz
Low Operating Current: 2.8 mA, typical
Fast Output Rise and Fall Times (5.9 ns and
6.2 ns)
Undervoltage Lockout
Output Short Circuit Protection
Overtemperature Protection
High-Speed, Microcontroller-Adaptable,
Pulse Width Modulator
