SGM48541/SGM48542
SGM48543/SGM48544/SGM48545
Single High-Speed, Low-Side Gate
Drivers with Negative Input Voltage Capability
GENERAL DESCRIPTION
FEATURES
The SGM48541/2/3/4/5 are single high-speed low-side
gate drivers for Power MOSFET switches. These
devices can provide rail-to-rail driving capability and
very small propagation delays (17.5ns, TYP). They also
provide 4A peak source current and 8A peak sink
current (asymmetrical drive) when VDD = 12V. The input
can withstand a maximum negative voltage of -10V.
● Asymmetrical Drive
4A Peak Source Current
8A Peak Sink Current
● 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:
-10V DC at Inputs
The operating voltage range is 4.5V to 25V. The
devices feature under-voltage lockout (UVLO) function.
After UVLO is triggered, the output remains low.
-2V, 200ns Pulse for Outputs
● Glitch-Free Operation at Power-Up and Power-
Down: Outputs are Pulled Low during Supply UVLO
● Fast Propagation Delays: 17.5ns (TYP)
● Fast Rise Time: 7ns (TYP)
The SGM48541 adopts separate output architecture.
The separate output structure with asymmetric drive
improves the immunity of the device to the parasitic
Miller conduction effect and reduces ground bounce.
● Fast Fall Time: 6.5ns (TYP)
● SGM48541 Separate Output Options Allow for
Tuning of Turn-on and Turn-off Currents
● SGM48541/4 Dual Input Design (Choice of an
Inverting (IN-) or Non-Inverting (IN+) Driver
Configuration)
The SGM48541/4 adopt a dual-input design. IN+ or IN-
can independently control the output of the driver. The
unused pin can be functioned as an enable control pin.
In order to ensure that the output remains low when an
input pin is floating, these input pins have internal
pull-up and pull-down resistors.
Unused Input Pin can be Used for Enable or
Disable Function
The input thresholds of these devices are compatible
with low voltage TTL and CMOS logic, which will not be
affected by VDD changes. A Schmitt trigger is used at
the input, and a wide range of hysteresis voltage is
designed to enhance the immunity.
● Input Pin Absolute Maximum Voltage Levels Not
Restricted by VDD Pin Bias Supply Voltage
● -40℃ to +140℃ Operating Temperature Range
