Description of Operation
The DrMOS multi-chip module incorporates a high-side MOS FET, low-side MOS FET, and MOS-FET driver in a single QFN package. Since the parasitic inductance between each chip is extremely small, the module is highly suitable for use in buck converters to be operated at high frequencies. The control timing between the high-side MOS FET, lowside MOS FET, and driver is optimized so that high efficiency can be obtained at low output-voltage. VCIN & DISBL# The VCIN pin is connected to the UVL (under-voltage lockout) module, so that the driver is disabled as long as VCIN is 4.3 V or less. On cancellation of UVL, the driver remains enabled until the UVL input is driven to 3.8 V or less. The signal on pin DISBL# also enables or disables the circuit. Voltages from -0.3 V to VCIN can be applied to the DISBL# pin, so on/off control by a logic IC or the use of a resistor, etc., to pull the DISBL# line up to VCIN are both possible.
VCIN L H H H DISBL# L H Open Driver State Disable (GL, GH = L) Disable (GL, GH = L) Active Disable (GL, GH = L)
The pulled-down MOS FET, which is turned on when internal IC temperature becomes over thermal shutdown level, is connected to the DISBL# pin. The detailed function is described in THDN section. PWM & LSDBL# The PWM pin is the signal input pin for the driver chip. The input-voltage range is -0.3 V to (VCIN + 0.3 V). When the PWM input is high, the gate of the high-side MOS FET (GH) is high and the gate of the low-side MOS FET (GL) is low.
PWM L H GH L H GL H L
The LSDBL# pin is the low-side gate disable pin for "Discontinuous Conduction Mode (DCM)" when LSDBL# is low. Figure 1 shows the typical high-side and low-side gate switching and inductor current (IL) during Continuous Conduction Mode (CCM) and low-side gate disabled when asserting low-side disable signal. This pin is internally pulled up to VCIN with 150 k resistor. When low-side disable function is not used, keep this pin open or pulled up to VCIN.

Figure 1.2 Typical Signals during Low-Side Disable Operation The PWM input is TTL level and has hysteresis. When the signal route from the control IC is high impedance, the tristate function turns off the high- and low-side MOS FETs. This function operates when the PWM input signal stays in the input hysteresis window for 100 ns (typ.). After the tri-state mode has been entered and GH and GL have become low, a PWM input voltage of 3.4 V or more is required to make the circuit return to normal operation.

Preliminary
The equivalent circuit for the PWM-pin input is shown in the next figure. M1 is in the ON state during normal operation; after the PWM input signal has stayed in the hysteresis window for 100 ns (typ.) and the tri-state detection signal has been driven high, the transistor M1 is turned off. When VCIN is powered up, M1 is started in the OFF state regardless of PWM Low or Open state. After PWM is asserted high signal, M1 becomes ON and shifts to normal operation.

Figure 3 Equivalent Circuit for the PWM-pin Input THWN & THDN This device has two level thermal detection, one is thermal warning and the other is thermal shutdown function. This thermal warning feature is the indication of the high temperature status. THWN is an open drain logic output signal and need to connect a pull-up resistor (ex. 51 k) to THWN for systems with the thermal warning implementation. When the chip temperature of the internal driver IC becomes over 115C, thermal warning function operates. This signal is only indication for the system controller and does not disable DrMOS operation. When thermal warning function is not used, keep this pin open.

Preliminary
This function makes high-side MOS FET and low-side MOS FET turn off for the device protection from abnormal high temperature situation and at the same time DISBL# pin is pulled low internally to give notice to the system controller. Figure 5 shows the example of two types of DISBL# connection with the system controller signal.
