3938 PRELIMINARY DATASHEET - 11/07/02 (Subject to change without notice) THREE PHASE POWER MOSFET CONTROLLER ABSOLUTE MAXIMUM RATINGS ( at TA = +25.
Features
* includes bootstrap capacitor charging current monitor, regulator under-voltage monitor, motor lead short-to-ground, and thermal shutdown. The A3938 is available in a choice of two packages: a 32-pin, rectangular PLCC suffix “EQ”; and 36-pin, QSOP, suffix “LQ”. FEATURES T Drives Wide Range of N-chaApplications
* VBB must be shorted to VREG. For this condition, the absolute max rating of 15V on VREG must be maintained to prevent damage to the 3938. 3938 Three Phase MOSFET Controller ELECTRICAL CHARACTERISTICS: Unless noted, otherwise: TA = 25°C, Vbb = 18 to 50 V, Clcap, Cboot = 0.1 uF, Cvreg = 10 uF, PWM3938 Distributors
