General Description
The Supertex HV430 is a high voltage PWM ring generator
integrated circuit. The high voltage outputs, Pgate and Ngate,
are used to drive the gates of external high voltage P-channel,
TP2640, and N-channel, TN2640, MOSFETs in a push-pull
configuration. Pulse by pulse over current protection are imple-
mented on both the P-channel and N-channel MOSFETs. The
RESET inputs functions as a power-on reset and as a low
voltage lockout, allowing for hot-swapping capabilities. The
FAULT output indicates over-current and low voltage lockout
conditions. It is active-low and open-drain to allow wire OR’ing of
multiple drivers.
P
GATE
and N
GATE
are controlled independently by logic inputs P
in
and N
in
when the mode pin is at logic high. A logic high on P
in
will
turn on the external P-channel MOSFET. Similarly, a logic high
on N
in
will turn on the external N-channel MOSFET. Lockout
circuitry prevents the N and P switches from turning on simulta-
neously.
For applications where a single control input is desired, the mode
pin should be connected to Gnd. The PWM control signal is then
input to the N
in
pin. A user-adjustable deadband in the control
logic assures break-before-make on the outputs, thus avoiding
cross conduction on the high voltage output during switching. A
logic high on Nin will turn the external P-Channel MOSFET on
and the N-Channel off, and vice versa. The IC can be powered
down by applying a logic low on the Enable pin, placing both
external MOSFETs in the off state.
