MAX1853

The MAX1853 monolithic, CMOS charge-pump voltage inverter in the ultra-small SC70

 

package features a low 15￿Ω output￿

resistance, which permits loads up to 30mA with

 

maximum efficiency. The MAX1853 is available with an operating frequency of 200kHz,

 

allowing optimization of supply current or external component size. Small external

 

components and micropower shutdown mode make this device ideal for both battery-

 

powered and board-level voltage conversion applications.

The MAX6817 dual switch debouncer provides clean interfacing of mechanical switches to

 

digital systems. The device accepts one or more bouncing inputs from a mechanical switch

 

and produces a clean digital output after a short, preset qualification delay. Both the switch

 

opening and closing bounces are removed. Robust switch inputs handle ±25V levels and are

 

±15kV ESD protected for use in harsh industrial environments. The MAX6817 features

 

single-supply operation from +2.7V to +5.5V. Undervoltage lockout circuitry ensures that the

 

output is in the correct state upon power-up. The MAX6817 is offered in a SOT package and

MAX6817

requires no external components.

The MAX1953/MAX1954/MAX1957 is a family of versatile, economical, synchronous current-

 

mode, pulse-width modulation (PWM) buck controllers. These step-down controllers are

 

targeted for applications where cost and size are critical. The MAX1953 operates at a fixed

 

1MHz switching frequency, thus significantly reducing external component size and cost.

 

Additionally, excellent transient response is obtained using less output capacitance. The

MAX1953

MAX1953 operates from low 3V to 5.5V input voltage and can supply up to 10A of output

current. Selectable current limit is provided to tailor to the external MOSFETs’ on-resistance

 

for optimal cost and performance. The output voltage is adjustable from 0.8V to 0.86VIN.

MAX4070

The MAX4069–MAX4072 low-cost, bidirectional, high-side, current-sense amplifiers are ideal

 

 

for monitoring battery charge and discharge currents in notebook PCs, cell phones, and other

 

portable equipment. The devices feature up to 24V input common-mode voltage range, low

 

100￿A supply current (which drops to only 10￿A in shutdown), and a total output error of less

 

than 1.5%. The wide 1.35V to 24V input common-mode range is independent of the supply

 

voltage, thus ensuring that the current-sense feedback remains accurate even when

 

connected to a battery pack in deep discharge.
