SGM48540
Single High-Speed, Low-Side Gate Driver with Negative Input Voltage Capability
The SGM48536/37/38/39/40 are single high-speed low- side gate drivers for MOSFET and IGBT power switches. These devices can provide rail-to-rail driving capability and very small propagation delays (18.5ns, 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.
The operating voltage range is 9V to 25V. The devices feature under-voltage lockout (UVLO) function. After UVLO is triggered, the output remains low.
The SGM48536 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.
The SGM48537 adopts 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.
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.
The SGM48536 is available in a Green SOT-23-6 package. The SGM48537/38/39/40 are all available in a Green SOT-23-5 package.
