A6862

Automotive 3-Phase Isolator MOSFET Driver

FEATURES AND BENEFITS

DESCRIPTION

• Three floating n-channel MOSFET drives

• Maintains V_GSwith 100 kΩ gate-source resistors

• Integrated charge pump controller

• 4.5 to 50 V supply voltage operating range

• Two independent activation inputs

• Single phase-enable input

• VCP and VGS undervoltage protection

• 150°C ambient (165°C junction) continuous

The A6862 is an n-channel power MOSFET driver capable

of controlling MOSFETs connected as a 3-phase solid-state

relay in phase-isolation applications. It has three independent

floating gate drive outputs to maintain the power MOSFETs in

the on-state over the full supply range with high phase-voltage

slew rates. An integrated charge pump regulator provides the

above battery supply voltage necessary to maintain the power

MOSFETsintheon-statecontinuouslywhenthephasevoltage

is equal to the battery voltage. The charge pump will maintain

with 100 kΩ gate source resistors.

APPLICATIONS

• 3-phase disconnect for ASIL systems up to level D

• Electric power steering (EPS)

• Electric braking

The three gate drives can be controlled by a single logic-level

input. In typical applications, the MOSFETs will be switched

on within 8 µs and will switch off within 1 µs.

• 3-phase solid-state relay driver

PACKAGE:

16-lead TSSOP with exposed thermal pad (suffix LP)

Undervoltage monitors check that the pumped supply voltage

and the gate drive outputs are high enough to ensure that the

MOSFETs are maintained in a safe conducting state.

TheA6862 is supplied in a 16-lead TSSOP (LP) with exposed

pad for enhanced thermal dissipation. They are lead (Pb) free,

with 100% matte-tin leadframe plating.
