Design an Efficient Reset Circuit: 05/01/03 EDN Design
Ideas / (added 1/05) When you work with microprocessors, you must ensure that when the power-supply voltage fluctuates to
the minimum permissible level, VL, that the processor's ALU continues to operate normally. Also, when you switch on the power supply, the ALU
must operate normally when the supply voltage equals or exceeds a certain high level, VH.... |

Design Low Duty Cycle Timer Circuits: 08/22/02 EDN Design
Ideas / (added 1/05) Designing astable circuits using the industry-standard 555 timer is a straightforward process when duty
cycles are 50% or greater. However, you must overcome the many pitfalls of low-duty-cycle circuits to arrive at a desired result. Using only
ideal components eases the design, but the components themselves are hard to obtain.... |

Dual Comparator Thermally Protects Lithium Ion Battery:
09/18/03 EDN Design Ideas / (added 1/05) Most manufacturers recommend that you don't change lithium-ion batteries at
temperatures lower than 0°C or higher than 50°C. You can monitor both thresholds by adding a thermistor and dual (window) comparator to a
lithium-ion battery charger (Figure 1). Set the low-temperature trip point at 2.... |
