SGM48524Q

Dual 5A, High-Speed, Low-Side Gate Driver

with Negative Input Voltage Capability

GENERAL DESCRIPTION

FEATURES

The SGM48524Q is a dual high-speed low-side gate

driver for MOSFET and IGBT power switches. It has

rail-to-rail driving capability and can sink and source up

to 5A peak current with capacitive loads. The

propagation delays are very short and well matched

between the two channels that make the device very fit

for applications that need accurate dual gate driving

such as synchronous rectifiers. The matched

propagation delays also allow for paralleling the two

channels when higher driving current is required, such

as for paralleled switches. The input voltage thresholds

are fixed, independent of supply voltage (V_DD) and are

compatible with low voltage TTL and CMOS logic.

Noise immunity is excellent due to the wide hysteresis

window between the input low and high thresholds. The

device has internal pull-up/pull-down resistors on the

input pins to ensure low state on the driver output when

the inputs are floating.

● AEC-Q100 Qualified for Automotive Applications

Device Temperature Grade 1

T_A= -40℃ to +125℃

● Two Independent Gate Drive Channels

● 4.5V to 18V Single Supply Range (V_DD)

● 5A Peak Source/Sink Pulse Current Drive

● Independent Enable Pin for Each Channel

● TTL and CMOS Compatible Logic Threshold

● Logic Levels Independent of Supply Voltage

● Hysteretic Input Logic for High Noise Immunity

● Outputs are Logic Low when Inputs are Floating

● Negative Voltage Handling Capability:

 -8V DC at Inputs

 -2V, 200ns Pulse for Outputs (OUTx)

● Glitch-Free Operation at Power-Up and Power-

Down: Outputs Pulled Low during Supply UVLO

● Fast Propagation Delays: 18ns (TYP)

● Fast Rise Time: 7ns (TYP)

● Fast Fall Time: 8ns (TYP)

The SGM48524Q is a dual non-inverting driver. It has

independent enable pins (ENA and ENB) for each

channel with active-high logic that can be left open for

normal operation because of internal pull-up to VDD.

● Delay Matching between Two Channels: 1ns (TYP)

● Channels can be Paralleled for Higher Drive Current

● Available in a Green SOIC-8 Package

The SGM48524Q is available in a Green SOIC-8

package. It operates over a temperature range of -40℃

to +125℃.
