NCV7512
FLEXMOSt Quad Low-Side
Pre-Driver
The NCV7512 programmable four channel low−side MOSFET
driver is one of a family of FLEXMOS^TM automotive grade products
used for driving logic−level MOSFETs. The product is controllable
by any combination of SPI (Serial Peripheral Interface) or parallel
inputs.
Programmable features include optional fault recovery, shorted
load detection threshold, fault retry timing, and fault masking mode.
The programmable refresh time allows operation in a
power−limiting PWM mode.
The device offers 3.3 V / 5 V compatible logic inputs and the serial
output driver can be powered from either 3.3 V or 5 V supplies.
Power−on reset of the supply pin provides for a controlled power up
and power down. Two enable inputs are supplied. ENA1 provides a
global on/off control with a reset function for internal circuitry.
ENA2 controls the output stage (during initialization).
Each channel independently monitors its external MOSFET’s
drain voltage for fault conditions. Shorted load fault detection
thresholds are fully programmable using an externally programmed
reference voltage and a combination of four discrete internal ratio
values. The ratio values are SPI selectable and allow different
detection thresholds for each pair of output channels. Open load fault
detection threshold is a function of a percentage of the power supply
voltage (VCC1). Fault information for each channel is 2−bit encoded
by fault type and is available through SPI communication.
The FLEXMOS family of products offers application scalability
through choice of external MOSFETs.
