EiceDRIVER™

2EDL8012/3/4 & 2EDL8112/3/4

Functional Description

The device is a level-shift 2-channel driver designed to support topologies with high-side and low-side

configurations. The high side is level shifted by the combination of an on-chip 120V rated bootstrap diode and

an external bootstrap capacitor. The device provides 2 A/3 A/4 A peak source current capability for high-side/

low side drivers and strong 5 A high-side and 6 A low-side sink current capability. This allows driving large

power MOSFETs with minimize switching losses during the transition through the MOSFET's Miller Plateau.

ꢀEDL8ꢂꢁx’s input pins support TTL logic levels independently of supply voltage. They are capable to withstand

voltages from -10 V to 20 V, allowing the device to interface with a broad range of analog and digital controllers.

The input stage features built-in hysteresis for enhanced noise immunity. The low-side and high-side gate

drivers are independently controlled and matched to typical 2 ns between the turn on and turn off of each

other.

ꢀEDL8ꢁꢁx’s input pins support TTL logic levels independently of supply voltage. They are capable to withstand

voltages from -10 V to 20 V and ground potential shifts from -8 to 15V, allowing the device to interfac with a

broad range of analog and digital controllers. The input stage features built-in hysteresis for enhanced noise

immunity. The low-side and high-side gate drivers are differentially controlled and matched to typical 1 ns

between the turn on and turn off of each other. The differential inputs provide inherent shoot-through

protection and ensure high-side and low-side outputs are never on at the same time.

The switching node (HS pin) is able to handle negative voltages down to –(24 - V_DD) V which allows the high-side

channel to be protected from inherent negative voltages caused parasitic inductance and stray capacitance.

Under-voltage lockout circuits are provided for both high- and low-side drivers. UVLO protects the system by

forcing the output low when the supply voltage is lower than the specified threshold.

The following sections describe key functionalities.

3.1

Supply Voltage

The absolute maximum supply voltage is 20 V. The minimum operating supply voltage is set by the under

voltage lockout function to a typical default value of 7.0 V. This lockout function protects power MOSFETs from

running into linear mode with subsequent high power dissipation.

3.2

Input Control

2EDL801x device responds to the two inputs signals (HI and LI) independently according to the following truth

table.
