3-PHASE POWER MOSFET CONTROLLER
— For Automotive Applications
3935
The A3935 is designed specifically for automotive applications that
require high-power motors. Each provides six high-current gate drive
outputs capable of driving a wide range of n-channel power MOSFETs.
A requirement of automotive systems is steady operation over a
varying battery input range. The A3935 integrates a pulse-frequency
modulated boost converter to create a constant supply voltage for
driving the external MOSFETs. Bootstrap capacitors are utilized to
provide the above battery supply voltage required for n-channel FETs.
Direct control of each gate output is possible via six TTL-compat-
ible inputs. A differential amplifier is integrated to allow accurate
measurement of the current in the three-phase bridge.
Diagnostic outputs can be continuously monitored to protect the
driver from short-to-battery, short-to-supply, bridge-open, and battery
under/overvoltage conditions. Additional protection features include
dead-time, VDD undervoltage, and thermal shutdown.
The A3935 is supplied in a choice of three packages, a 44-lead
PLCC with copper batwing tabs (suffix ED), a 48-lead low profile QFP
with exposed thermal pad (suffix JP), and a 36-lead 0.8 mm pitch SOIC
(suffix LQ).

thermal shutdown circuitry. These conditions
can be tolerated, but should be avoided.
