MP6601 – 35V, 2.5A, STEPPER MOTOR DRIVER W/ INTERNAL CURRENT SENSE
Thermal Resistance (4)
QFN-24 (5mmx5mm)............. 36 ....... 8 ....°C/W
TSSOP-28 EP........................ 32 ....... 6 ....°C/W
θJA
θJC
ABSOLUTE MAXIMUM RATINGS (1)
Supply voltage (VIN) ........................ -0.3V to 40V
xOUTx voltage (VA/BOUT1/2) .............. -0.7V to 40V
VCP, CPB ................................. VIN to VIN + 6.5V
ESD rating (HBD).......................................... 2kV
All other pins to AGND................... -0.3V to 6.5V
NOTES:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature TJ (MAX), the junction-to-
ambient thermal resistance θJA, and the ambient temperature
TA. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by PD (MAX) = (TJ
(MAX)-TA)/θJA. Exceeding the maximum allowable power
dissipation produces an excessive die temperature, causing
the regulator to go into thermal shutdown. Internal thermal
shutdown circuitry protects the device from permanent
damage.
(2)
