Description
The BridgeSwitch™ family of integrated half-bridges dramatically
simplifies the development and production of high-voltage inverter
driven 2- or 3-phase PM or BLDC motor drives. It incorporates two
high-voltage N-channel power FREDFETs with low and high-side drivers
in a single small-outline package. The internal power FREDFETs offer
ultra-soft and ultrafast diodes ideally suited for hard switched inverter
drives. Both drivers are self-supplied eliminating the need for an
external auxiliary power supply. BridgeSwitch provides a unique
instantaneous phase current output signal simplifying implementation of
sensor-less control schemes. The low-profile, compact footprint surface
mount package offers extended creepage distances and allows heat
sinking of both power FREDFETs through the printed circuit board.
BridgeSwitch offers internal fault protection functions and external
system level monitoring. Internal fault protection includes cycle-by-

BridgeSwitch
BridgeSwitch Functional Description
BridgeSwitch combines two high-voltage power FREDFETs, gate
drivers and controllers into a single package. The FREDFETs are
connected in a half-bridge configuration where their diode structure
(ultra-soft and ultra-fast recovery) makes them ideal for hard-
switched inverter-based motor drivers.
To reduce external components, the drive controllers feature integrated
high-voltage current sources, allowing them to draw current directly
from the high-voltage DC Bus. The high-side controller provides
high-side status updates to the low-side controller which generates
an instantaneous phase-current output signal (BRD126X). This
unique capability allows the implementation of a sensor-less
motor-control scheme. The controllers also ensure that the FREDFET
turn-off is faster than turn-on resulting in an optimal balance
between thermal performance and EMI.
BridgeSwitch offers integrated fault protection and system level
monitoring via a bi-directional bussed single-wire status interface.
Internal fault protection includes cycle-by-cycle current limit for both
FREDFETs as well as two-level thermal overload protection.
BridgeSwitch offers sophisticated DC-bus sensing, providing four
undervoltage levels and one overvoltage level, and can also support
external sensors such as an NTC. Figure 3 shows the functional block
diagram of the device along with key features.
BYPASS LOW-SIDE Pin and HIGH-SIDE Pin Regulator
The BYPASS LOW-SIDE pin and the BYPASS HIGH-SIDE pin have
internal regulators that charge the BYPASS LOW-SIDE pin capacitor
and the BYPASS HIGH-SIDE pin capacitor to V
BPL
and V
BPH
, respec-
tively. A current source connected to HIGH-SIDE DRAIN charges the
BYPASS LOW-SIDE capacitor. Another current source connected to
HIGH-SIDE DRAIN charges the BYPASS HIGH-SIDE capacitor
whenever the low-side power FREDFET turns on. Both current sources
start charging once the HD pin voltage reaches V
HD(START)
(min. 50 V).
The BYPASS LOW-SIDE and the BYPASS HIGH-SIDE pins are the
internal supply voltage nodes for the low-side and the high-side
controllers and Gate drivers. When the low-side or the high-side
power FREDFETs are on, the device operates from the energy stored
in the BYPASS LOW-SIDE pin capacitor or the BYPASS HIGH-SIDE pin
capacitor, respectively.
In addition, there are shunt regulators clamping the BYPASS LOW-SIDE
pin to V
BPL(SHUNT)
and the BYPASS HIGH-SIDE pin to V
BPH(SHUNT)
when
current is provided to the BYPASS LOW-SIDE pin and the BYPASS
HIGH-SIDE pin from an external DC source through resistors (see
R
SL
and R
SH
in Figure 6). External supply voltage V
SUP
is greater than
bypass shunt regulator voltage V
BPX(SHUNT)
plus the voltage drop of
bootstrap diode D
SH
. A typical value is V
SUP
= 17 V. Resistors R
SL
and
R
SH
limit the external supply current to less than 12 mA (2-5 mA
recommended). Shorting BPL pins or BPH pins from separate devices
directly together is not recommended.
BYPASS LOW-SIDE Pin and HIGH-SIDE Pin
Undervoltage Threshold
The BYPASS LOW-SIDE pin and BYPASS HIGH-SIDE pin undervoltage
circuitries disable the respective power FREDFET when either the
BYPASS LOW-SIDE pin voltage or the BYPASS HIGH-SIDE pin voltage
drops below V
BPL
-V
BPL(HYST)
or V
BPH
-V
BPH(HYST)
, respectively, in steady-state
operation. Once either the BYPASS LOW-SIDE pin voltage or the
BYPASS HIGH-SIDE pin voltage fall below this threshold, it must rise
back up to V
BPL
or V
BPH
, respectively to enable power FREDFET switching.
BYPASS LOW-SIDE Pin and HIGH-SIDE Pins
Capacitor Selection
Capacitors connected to the BYPASS LOW-SIDE pin and BYPASS
HIGH-SIDE pin supply bias current for the low-side and the high-side
controller and deliver the required Gate charge for turning on the
low-side or the high-side power FREDFET. The BYPASS HIGH-SIDE pin
capacitor supplies the high-side controller bias current over a time
interval which is a function of the high-side commutation duty ratio and
PWM frequency. The recommended maximum voltage ripple at the
BYPASS HIGH-SIDE pin capacitor over this time interval is 250 mV. The
minimum required capacitance value for both bypass low-side and
bypass high-side is 0.33
mF.
The recommended bypass low-side
capacitance is 1
mF.
Given application operating conditions determine the required bypass
high-side capacitance to keep ripple voltage below 250 mV. Figure 7
depicts the minimum recommended BYPASS HIGH-SIDE pin capaci-
tance as function of high-side commutation duty ratio D
HS
and PWM
frequency.

Note that multilayer chip capacitors (MLCC) can exhibit a significant

(according to Figure 7) needs to take the possible capacitance
reduction into account when biasing at V

. Refer to the respective
