General
The NCV7703B Triple Half Bridge Driver provides drive
capability for 3 Half?Bridge configurations. Each output
drive is characterized for a 500 mA load and has a typical
1.4 A surge capability. Strict adherence to integrated circuit
die temperature is necessary, with a maximum die
temperature of 150 ° C. This may limit the number of drivers
enabled at one time. Output drive control and fault reporting
are handled via the SPI (Serial Peripheral Interface) port.
An Enable function (EN) provides a low quiescent sleep
current mode when the device is not being utilized. A pull
down is provided on the EN, SI and SCLK inputs to ensure
they default to a low state in the event of a severed input
Power Up/Down Control
A feature incorporated in the IC is an under voltage
lockout circuit that prevents the output drivers from turning
on unintentionally. V CC and V S are monitored for
undervoltage conditions supporting a smooth turn?on
transition. All drivers are initialized in the off (high
impedance) condition, and will remain off during a V CC or
V S undervoltage condition. This allows power up
sequencing of V CC , and V S up to the user. Once V CC is out
of UVLO, SPI communication can begin regardless of the
voltage on V S . However, drivers will remain off if V S is in
an undervoltage condition. Hysteresis in the UVLO circuits
results in glitch free operation during power up/down.
signal. A pull?up is provided on the CSB input disabling SPI
communication in the event of an open CSB input.
