EPC’s ePowerTM Stage and Chipset integrate input logic interface, level shifting, bootstrap charging
and gate drive buffer circuits along with eGaN output FETs. Integration is implemented using EPC’s
proprietary GaN IC technology. The end result is a Power Stage that translates logic level input to
high voltage and high current power output that is smaller in size, easier to manufacture, simpler to
design and more efficient to operate.

General Description
The EPC23101 ePowerTM IC integrates a half-bridge gate driver with an
internal high side FET. It is designed as part of a chipset with a companion
low side eGaN® FET such as the EPC2302. Integration is implemented
using EPC’s proprietary GaN IC technology. The high side monolithic
chip integrates input logic interface, level shifting, bootstrap charging
and gate drive buffer circuits along with a high side eGaN output FET.
The low side output FET is driven by the gate driver output of the GaN IC
to configure a half-bridge power stage.
The charging path for the floating bootstrap supply is activated with LSIN
logic. It uses eGaN FET as the series switch that minimizes power losses
by eliminating reverse recovery. This synchronous bootstrap charging
circuit also minimizes voltage drop in the charging path.
The on-chip gate drive buffers practically eliminate effects of common
source inductance and gate drive loop inductance. Power loop inductance
is minimized by compatible high side to low side pinout configuration
that facilitates optimal layout technique. Switching times are tuned by
external resistors to achieve 1–3 ns rise and fall times from 0–48 V at full
load current. Over-voltage spikes can be controlled to less than +10 V
above rail and –10 V below ground during hard switching transitions by
choosing the tuning resistors, RBOOT and RDRV .
Protection is provided by high side and low side under-voltage lockout
to keep both FETs off at low supply voltages. If the supply voltages drop
even lower or are lost while VIN is active at greater than 10 V, another
active pull-down circuit is used with biasing from VIN to prevent
destructive turn-on of both FETs from gate to drain leakage..
The EPC23101 IC only requires an external 5 V VDRV power supply. Internal
low side and high side power supplies, VDD and VBOOT , are generated
from the external supply via a series connected switch. The internal
supplies can be cut off to save quiescent power by turning off the switch
with 5 V applied to the EN pin.
EPC – POWER CONVERSION TECHNOLOGY LEADER | EPC-CO.COM | ©2023 |
Robust level shifters from low side to high side channels are designed to
operate correctly even at large negative clamped voltage and to avoid
false trigger from fast dv/dt transients including those driven by external
sources or other phases.
The EPC23101 IC is capable of interfacing to digital controllers that use
standard 3.3 V or 5 V CMOS logic levels. Separate and independent high
side and low side logic control inputs allow external controllers to set
fixed or adaptive dead times for optimal operating efficiency. Cross
conduction prevention logic keeps both FETs off when logic inputs are
both high at the same time.
The FET gate drive voltages are derived from the internal low side and
high side power supplies. Full gate drive voltages are only available after
the HSIN and LSIN PWM inputs start to operate for a few cycles.

only through natural convection. The test used JEDEC Standard 4-layers PCB with 2oz top and bottom surface layers and
1oz buried layers. RθJA_EVB is measured using EPC90142 EVB with no forced air cooling, this rating is more indicative of

Input Voltage (VIN to GND)
Output Switch Node, 3rd Quadrant Mode [4]
Output Switch Node, Transient PW= 10 V for the IC to be enabled. Below the minimum VIN the pass-transistor between VDRV
and VDD will be off. Same condition when VDD disable pin, EN, is connected to 5 V.
Note 4: The output switching node (SW) is clamped above VIN by the HS FET or below GND by the LS FET at their respective source drain voltage
in the 3rd quadrant. This is an operating condition when both HS and LS FETs are in the off states during the dead time period which
is set by the application circuit with typical value of 15 ns. The Absolute Minimum Rating is determined by LS FET 3rd quadrant clamp
voltage below GND. Conversely the Absolute Maximum Rating is determined by HS FET 3rd quadrant clamp voltage above VIN. The time
duration that the device can stay in the negative clamp voltage region is subjected to the amount of load current, power dissipation
and maximum allowed junction temperature.
Note 5: During HS FET or LS FET turn-on transitions with hard switching conditions, the fast di/dt of the HS FET or LS FET coupled with the
power loop inductance (VPeak = LPower loop · di/dt) would cause a transient over-voltage spike above VIN or below GND. The Absolute
Minimum Rating is amount of peak voltage spike, caused by LS FET di/dt, below GND for less than 2 ns pulse duration. Conversely the
Absolute Maximum Rating is amount of peak voltage spike, caused by HS FET di/dt, above VIN, for less than 2 ns pulse duration.
Note 6: For interfacing with analog controller operating from 12 VCC and outputting a 12 V drive signal, a resistor network in series should be
inserted to divide the voltage to acceptable VIH level and limit the input current into the logic input pins HIN and LIN which is clamped to
the VDD supply by ESD protection network.
Note 7: LIN commands LS FET to turn-on to charge bootstrap supply through sync boot.
Note 8: Internal logic follows HSIN, LSIN respectively but cross conduction lockout logic prevents both HS and LS FETs to turn on together as
commanded if both HSIN and LSIN are set to logic “high”.
