Detailed Description
Logic Inputs
The MAX15070A/MAX15070Bs’ logic inputs are pro-
tected against voltage spikes up to +16V, regardless of
the V+ voltage. The low 10pF input capacitance of the
inputs reduces loading and increases switching speed.
These ICs have two inputs that give the user greater
flexibility in controlling the MOSFET. Table 1 shows all
possible input combinations. The difference between the
MAX15070A and the MAX15070B is the input threshold
voltage. The MAX15070A has TTL logic-level thresholds,
while the MAX15070B has HNM (CMOS-like) logic-level
thresholds (see the Electrical Characteristics ). Connect
IN+ to V+ or IN- to GND when not used. Alternatively,
the unused input can be used as an on/off control input
(Table 1).
Undervoltage Lockout (UVLO)
When V+ is below the UVLO threshold, the n-channel is
on and the p-channel is off, independent of the state of
the inputs. The UVLO is typically 3.45V with 200mV typi-
cal hysteresis to avoid chattering. A typical falling delay
of 2 F s makes the UVLO immune to narrow negative tran-
sients in noisy environments.

Driver Outputs
The ICs provide two separate outputs. One is an open-
drain p-channel, the other an open-drain n-channel. They
have distinct current sourcing/sinking capabilities to inde-
pendently control the rise and fall times of the MOSFET
gate. Add a resistor in series with P_OUT/N_OUT to slow
the corresponding rise/fall time of the MOSFET gate.
